Why are the Yangtze River and Yellow River called the mother rivers of the Chinese nation? urgent. . .

The Yellow River is the mother river of the Chinese nation. As the birthplace of Chinese civilization, it maintains the blood of the descendants of Yan and Huang. It is a symbol of the national spirit and national emotions of the Chinese nation.

The Yellow River, like a lion with its back arched and head held high, crosses the mountains of Qinghai and Gansu Provinces from the Qinghai-Tibet Plateau; crosses the Hetao Plains of Ningxia and Inner Mongolia; and gallops between Shanxi and Shaanxi Among the high mountains and deep valleys; break through the "Dragon Gate", turn east at the foot of Huashan Mountain in Xiyue, cross the North China Plain, and rush to the coast of the Bohai Sea. It flows through 9 provinces and regions, gathering more than 40 main tributaries and more than 1,000 streams, with a journey of 5,464 kilometers and a drainage area of ​​more than 750,000 square kilometers. It is the second largest river in China. The average annual precipitation in the entire basin is about 400 mm, while the average annual runoff of the Yellow River is only 57.4 billion cubic meters, ranking eighth among Chinese rivers. Within the basin, together with the downstream Henan and Shandong riverside areas, there are more than 200 million acres of cultivated land and a population of about 100 million. The Yellow River is rich in water conservancy resources and has numerous underground mineral deposits in the basin. People of all ethnic groups have worked hard here for generations, creating a splendid ancient culture and becoming the cradle of the Chinese nation.

There have been many theories about the source of the Yellow River in history. As early as the first half of the 7th century AD, some people proposed that Kariqu was the true source of the Yellow River, but it was not recognized. In 1280 AD, Dushi of the Yuan Dynasty and Lashi of the Qing Dynasty in 1704 reached Xingxiu Sea in order to explore the source of the river. Therefore, the saying that Xingxiu Sea is the source of the river has been circulated for many years. After the founding of the People's Republic of China, the Yellow River Water Conservancy Commission organized a river source inspection team in August 1952 and regarded Yogu Zongliqu as the true source of the Yellow River. Over the past 20 years, although mistakes have been made, many people have raised questions. It was not until the summer of 1978 that another Heyuan expedition team was organized to conduct on-the-spot investigation in the Heyuan area. It was found that in the west of the Heyuan area, there were three rivers flowing into the Xingxiu Sea. They were Zaqu, Yoguzongliequ and Kariqu. The process of Zhaqu is the shortest and the water volume is small, so it can only be regarded as a tributary of Yuegu Zongliqu. Compared with Yuegu Zongliqu, Kaliqu is nearly 30 kilometers longer than Yuegu Zongliqu, with a drainage area of ​​700 square kilometers and more than twice the water volume. Therefore, there is sufficient basis for determining that KaRiqu is the true source of the Yellow River. Kaliqu originates from Gezigeya Mountain at the northern foot of Bayan Har Mountain. Gezigeya Mountain is 4,800 meters above sea level. The clear water overflowing from several springs at the foot of the mountain is the first flow of the Yellow River that "roars for thousands of miles and touches the dragon's gate".

The Cradle of the Chinese Nation

"Yellow River, you are the cradle of the Chinese nation. The 5,000-year-old ancient culture originated from you..." This is the well-known song "Ode to the Yellow River" 》lyrics. Whenever people sing this song, they will be immersed in infinite memories of the Yellow River.

As early as the Paleolithic Age 800,000 years ago, the ancestors of the Chinese nation lived a life of hunting and gathering in the Yellow River Basin. More than 2,000 primitive village sites have been discovered in the Yellow River Basin, which shows that during the Neolithic Age, our ancestors settled on this vast land and engaged in primitive agricultural production.

In the middle of the Neolithic Age, the Huangdi tribe scattered on the Loess Plateau in the middle reaches of the Yellow River, together with the Chiyou tribe and the Yandi tribe at that time, were the same three tribes in ancient China. They live a nomadic life that moves erratically. Later, Emperor Yan joined forces with Emperor Huang to attack and kill Chi You. Soon, the people of the Yandi and Huangdi tribes gradually merged and settled in the Shaanxi, Gansu, and Shanxi regions, and they jointly developed the middle and lower reaches of the Yellow River.

The Xia, Shang and Zhou dynasties that entered slave society more than 3,500 years ago are all descendants of the Yellow Emperor. They call themselves "Hua" or "Xia". The Chinese are the predecessors of the Han, so the Han people regard the Yellow Emperor as their ancestor and call themselves descendants of the Yellow Emperor (also known as Yanhuang). At that time, the Chinese people lived in the Central Plains area. People believed that the Central Plains lived in all directions, so they also called this area "China". Later, Chinese culture spread to all parts of the country, and the word "Zhonghua" became the name of the entire China.

For thousands of years, the Yellow River Basin was the center of feudal rule, and the working people's struggles against oppression continued one after another. Chen Sheng and Wu Guang in the late Qin Dynasty, Red Eyebrows, Bronze Horses, and Yellow Turbans in the Han Dynasty, Wagang Army in the late Sui Dynasty, Huang Chao and Wang Xianzhi in the Tang Dynasty, Li Zicheng and Zhang Xianzhong in the late Ming Dynasty, etc., all performed in the land of the Yellow River Basin. A magnificent historical drama. During the War of Resistance Against Japan and the War of Liberation, the Shaanxi-Gansu-Ningxia region was a reliable revolutionary base for the Chinese people until the founding of the great People's Republic of China.

In the long history, the great Yellow River has nurtured the Chinese nation; the children of the Chinese nation have created a splendid ancient culture. We are proud of the Yellow River and sing for the Yellow River.

Yangtze River

The Yangtze River is the largest river in China. The total length of the main stream is 6,397 kilometers (with the Tuotuo River as the source), which is generally called 6,300 kilometers. The total area of ​​the basin is more than 1.8 million square kilometers, and the average annual seawater inflow is about 960 billion cubic meters. The Yangtze River ranks third in the world in terms of the length of its main stream and the amount of water entering into the sea.

The Tuotuo River, the upper source of the Yangtze River, originates from the Geladandong Snow Mountain in the Tanggula Mountains on the southwest border of Qinghai Province. It merges with the southern source of the Yangtze River and is called the Tongtian River. It flows south to the mouth of the Batang River in Yushu County and reaches Sichuan. The city of Yibin in the province is called the Jinsha River; the area below Yibin was originally called the Yangtze River, and the area below Yangzhou was formerly called the Yangtze River. The Yangtze River flows through Tibet, Sichuan, Chongqing, Yunnan, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and other provinces and cities, and flows into the East China Sea in Shanghai.

There are tributaries such as Yalong River, Minjiang River, Tuojiang River, Jialing River, Wujiang River, Xiangjiang River, Hanjiang River, Ganjiang River, Qingyijiang River and Huangpu River. It intersects with the Beijing-Hangzhou Grand Canal in Zhenjiang City, Jiangsu Province.

The upper reaches of the Yangtze River above Yichang City in Hubei Province have many rapids and shoals; the middle reaches between Yichang and Hukou in Jiangxi Province have developed meanders and many lakes (Poyang and Dongting Lakes are the largest); below Hukou there are Downstream, the river is wide and there is Chongming Island formed by alluvial at the river mouth. The Yangtze River is rich in water volume and water conservancy resources. During the flood season, a 10,000-ton ship can reach Wuhan, and a small ship can go back to Yichang.

The Yangtze River Basin is a densely populated and economically prosperous region in China. Important cities along the river include Chongqing, Wuhan, Nanjing, and Shanghai.

The total amount of water energy available for development in the Yangtze River reaches 200 million kilowatts, making it the river with the richest water energy in China. The main stream of the Yangtze River has a navigation mileage of more than 2,800 kilometers and is known as the "golden waterway".

The Yangtze River reaches the majestic and steep Three Gorges section (Qutang Gorge, Wu Gorge, and Xiling Gorge) from Fengjie, Chongqing to Yichang, Hubei. The world's largest water conservancy project, the Three Gorges Project, is located in Sandouping in the middle section of Xiling Gorge. .

The Yangtze River is the largest river in China and one of the largest rivers in the world. Its main stream is more than 6,300 kilometers long. It originates from the southwest side of the Geladandong Snow Mountain, the main peak of the Tanggula Mountains on the Qinghai-Tibet Plateau (33°28′ north latitude). , 91° 08′ east longitude). The main stream flows through 10 provinces, municipalities and autonomous regions including Qinghai, Tibet, Sichuan, Yunnan, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai, and flows into the East China Sea. The total length is about 6,300 kilometers (if Dangqu is the source, the total length of the Yangtze River should be 6,403 kilometers), ranking third in the world. The basin is between 24°30′-35°45′ north latitude and 90°33′-112°25′ east longitude, covering an area of ​​more than 1.8 million square kilometers (excluding the Huaihe River Basin), accounting for about 1/5 of the country’s total land area. The average annual seawater inflow reaches 1 trillion cubic meters, ranking third in the world. In ancient times, it was simply called Jiang. After the Six Dynasties, it was called Dajiang and Yangtze River.

Mainstream Overview: Each section of the Yangtze River's main stream has different names: the source to Dangqukou (the river is called "Qu" in Tibetan) is called the Tuotuo River, the main source of the Yangtze River, with a length of 358 kilometers; The Batang River estuary in Yushu County, Qinghai Province, is called Tongtian River, 813 kilometers long; the Batang River estuary to the Minjiang River estuary in Yibin, Sichuan Province, is called the Jinsha River, 2,308 kilometers long; the Yibin Minjiang estuary to the Yangtze River estuary, about 2,800 kilometers long, commonly known as The Yangtze River, of which the stretch from Yibin to Yichang in Hubei Province is called the "Chuan River" (the stretch of the Three Gorges River from Fengjie to Yichang is also called the "Xiajiang River"), the stretch from Zhicheng in Hubei Province to Chenglingji in Hunan Province is called the Jingjiang River, and the stretch between Yangzhou and Jiangsu Province is The area below Zhenjiang is also called the Yangtze River. Within the basin, plateaus and mountains account for 65.6%; hills account for 24%; plains and lowlands account for 10.4%.

There are 48 tributaries of the Yangtze River with a basin area of ​​more than 10,000 square kilometers; those with a basin area of ​​more than 50,000 square kilometers include the Yalong River, Minjiang River and their tributaries Dadu River, Jialing River, Wujiang River, Yuanjiang River, Xiangjiang River, Hanjiang River and Ganjiang River Jiang et al. 9. Among them, the Yalong River, Minjiang River, Jialing River and Han River exceed 100,000 square kilometers, with the Jialing River basin having the largest area, about 160,000 square kilometers.

Most of China's freshwater lakes are distributed in the middle and lower reaches of the Yangtze River. The larger ones include Poyang Lake, Dongting Lake, Taihu Lake and Chaohu Lake.

The Yangtze River originates between the Bayan Hara Mountains and the Tanggula Mountains on the Qinghai-Tibet Plateau, on the southwest side of Geladandong, the main peak of the Tanggula Mountains. Glaciers are widespread here, and the melted water from ice and snow is the source of the Yangtze River. From the source of the river to Renhaikou, it can be divided into three major sections. Above Yibin in Sichuan is the upper reaches; from Yibin to Yichang in Hubei is the middle reaches; below Yichang is the lower reaches. The upstream section is about 3,500 kilometers long. The Chumar River is the northern source of the Yangtze River; the Mulu Wusu River is the southern source of the Yangtze River. It has a longer flow and a larger amount of water. According to the principle of "the source of the river is far away", its The Tuotuo River, the longest tributary, should be the main source of the Yangtze River. The section from the mouth of Dangqu River to Yushu, Qinghai is called Tongtian River, which is 813 kilometers long. The river channel is wide and the water flow is gentle. From Yushu to Yibin, it is called the Jinsha River, or Lishui in ancient times. It flows from north to south, passes through the Hengduan Mountains, turns northeast near Shigu, Yunnan, and enters the Sichuan Basin. It joins the Minjiang River in Yibin, with a total length of 2,300 kilometers. It is only called the Yangtze River from Yibin onwards. The middle reaches is about 1,000 kilometers long and is commonly known as the Sichuan River because it flows through the Sichuan Basin. From Yibin to Chongqing, the river course is quite winding. From Baidi Mountain in Fengjie to Nanjinguan in Yichang, the river passes through the Grand Canyon in the border mountains of Sichuan and Hubei. From west to east there are Qutang Gorge, Wu Gorge, and Xiling Gorge, collectively known as the Three Gorges, with a total length of 204 kilometers and beaches. There are many rapid currents and a huge drop in the river. It has been called a natural danger of the Yangtze River since ancient times. The downstream section is about 1,850 kilometers long. The river has a very small drop and slow flow. The river surface is wide, generally more than two kilometers, and the narrowest point is 650 meters. The river course is very winding, especially the section from Zhijiang in Hubei to Chenglingji in Hunan. It was called Jingjiang in ancient times and is known as the "nine-winding ileum". Due to the slow flow rate and heavy sedimentation, whenever the flood season comes, it is very easy to cause flooding disasters. Since ancient times, there has been a saying that "the Yangtze River is thousands of miles long, but the Jingjiang River is dangerous." From Yichang to Wuhu, there are many lakes on both sides of the river, among which Dongting Lake and Poyang Lake are the largest. Dongting Lake is a natural reservoir of the Yangtze River. After the river enters Jiangsu, it is blocked by the mountains and flows northeast around the Ningzhen Mountains. From the bottom of Zhenjiang, turning to Shunan and entering the delta area, the terrain is flat, dotted with lakes, and the waterways are intertwined like a network, creating a scene of a water town and a country. The mouth of the river is actually 80 kilometers wide, presenting a spectacular view of the river and the sea. There are many famous mountains and swamps on both sides of the Yangtze River, with beautiful scenery and many tourist attractions. Due to the long process, wide drainage basin, fertile land and convenient irrigation, there is a "land of abundance" in the middle reaches and a "land of fish and rice" in the lower reaches, with rich products.

Although the cradle of the Chinese nation is in the Yellow River Basin, according to historical records, after King Wu of Zhou destroyed the Yin Dynasty, his territory reached as far south as the Yangtze River Basin. Since then, the Yellow River and Yangtze River Basins have become the focus of China's historical and cultural development. There are many famous cities along the river, such as Chongqing, Yichang, Wuchang, Nanjing, Shanghai, etc. Shanghai is China's largest industrial and commercial city. There are many scenic spots and historic sites on both sides of the Taiwan Strait, which are precious materials for understanding Chinese history. There are also many myths and legends, which are precious heritage of Chinese literature. The trunk and tributaries of the Yangtze River have been the main water transportation arteries in southern China that traverse east and west and connect north and south since ancient times. The total length of the waterway is more than 80,000 kilometers. A 10,000-ton ship can reach Nanjing, a 3,000-ton ship can reach Hankou, a 1,000-ton ship can reach Chongqing, and a 500-ton ship can reach Yibin.

The first footprints of human civilization were imprinted on the banks of rivers. Therefore, early human civilization is also called the river civilization. The regular flooding of the narrow Nile River created a fertile plain delta, which gave rise to the pyramids and the Sphinx. The 7,000-year-old culture of ancient Egypt remains, singing a "primitive ode to water"; the milky Indus and Ganges rivers Side by side, they opened the door to ancient Indian civilization and became the "eternal Nirvana". They also created the Taj Mahal, a splendid architectural pearl, and the eternal love myth. The Euphrates and Tigris rivers gave birth to the ancient Babylonian civilization that illuminated mankind and were known as "The cradle of world civilization", the Code of Hammurabi and the Hanging Gardens have become mysterious silhouettes of ancient civilization.

Human beings live in pursuit of water and grass. Wherever there is water, there are people. As the only remaining civilization in modern society among the four ancient civilizations, the Chinese civilization has a close relationship with water for its survival and reproduction. The Yandi tribe and the Huangdi tribe formed an alliance and defeated Chiyou on the banks of the Yellow River, and gradually settled in the Central Plains. Through conflicts and mergers, various ancient tribes jointly developed the middle and lower reaches of the Yellow River, making the Yellow River Basin the cradle of the Chinese nation. Cangjie invented Chinese characters, and Chinese civilization continues to this day. Not to mention, the legend of Yanhuang. The Banpo people and the Hemudu people each inhabited the Yellow River and the Yangtze River. They settled in the right places and cultivated wheat and rice, which opened the source of China's agricultural industry. The Yangtze and Yellow Rivers are actually the source of Chinese civilization.

However, when monstrous floods slap on the back of modern civilization; when the earth roars and tsunamis sweep away thousands of homes; when deprivation comes, people pour their tears of sadness into the rivers and oceans that gave birth to their ancestors; How many people still just curse the water sources that once benefited mankind?

However, when the Yellow River is truly rolling a turbid yellow stream; when the Yangtze River begins to call to the Yellow River: "Yellow River, Yellow River, I am also the Yellow River!"; when the eight hundred miles of Dongting is shrinking day by day, the residents along the coast are How many people still remember at this moment that their mother river, the Yellow River and the Yangtze River, has withstood the plunder of thousands of generations?

As descendants of Yan and Huang, before legends and disasters, have we ever thought about: How deeply have we been benefited by water?

Looking back at history: Water not only gave birth to the lives of our ancestors and the long-standing Chinese civilization, but also deepened the connotation of Chinese civilization and enriched the glorious Chinese culture.

Singing through the water, the autumn water is beautiful. The gurgling flow of "National Style" is the low singing of water, and the ancient and beautiful rhyme creates a realistic poetic style.

Quzi came to Linjiang and went to his country to miss his hometown. He saw "Dongting waves under the wooden leaves". He was relegated to wandering and wandered around in search of things. As for Miluo, he bouldered and sank into the river. "Li Sao" started the romantic poetry style and spread the patriotic sentiment through the ages.

Water flows through the blood vessels of the descendants of Yan and Huang, and also allows our ancestors to baptize their thoughts and lives.

Tzu said on the river: "The deceased is so good that he never gives up day and night."

Laozi said: "The best thing is like water. Water is good for all things and does not fight for it. It is disliked by everyone, so it is a good thing. On the road."

Shao Gong admonished King Li: "It is better to guard the people's mouth than to guard the river. If the river collapses, many people will be hurt."< /p>

“Water can carry a boat, but it can also overturn it.” Li Shimin, Emperor Taizong of the Tang Dynasty, also learned from running water the principles of governing the country.

Fan Zhongyan stood in the Yueyang Tower overlooking the Dongting, and shocked the world with his words: "Be worried about the world's worries first, and be happy after the world's happiness."

The rolling river flows eastward. And water is no longer the original water. When wise people cry out: "Don't let human tears become the last drop of water." We begin to pay attention to the source that once favored us and gave us life.

The water system that once gave birth to human civilization is no longer as clear as before, and has been plundered, resisting human greed and revenge; the peace of the blue sea has become a thing of the past, and the flushed sea exudes rancid odor; the desert The clear streams in the mountains are shrinking; the fish and shrimps in the lakes are dying; the clear springs in the mountains have become rare. ． ． ． ． ． As a result, Niguala Falls became a scenery; then, the West Lake became a paradise; then, Guilin's landscape is unparalleled in the world. However, we still see that the water belonging to the landscape is being polluted and damaged. We began to complain: "Phoenix's commercial atmosphere today is too strong, and it is no longer the Phoenix in "Border Town"." We regretted: "Jiuzhaigou has changed its flavor during development." We despaired: "There is no last Shangri-La in nature."

Dayu once passed through the house three times to control floods without entering. His spirit will be praised by future generations.

It is said that after Shun succeeded Yao as the leader of the tribal alliance, he personally inspected the flood control situation and appointed Gun's son Yu to continue the flood control. After receiving the order, Dayu first looked for lessons from previous flood control failures, and then led Qi, Qi and others as well as his disciples and assistants We traveled through mountains and rivers together, briefly inspecting the source, upstream and downstream of the water flow, and piled some stones or cut down trees in important places as marks for reference during flood control. After conducting in-depth research, Dayu finally concluded that the method of controlling water lies in diversion.

Li Bing, governor of Shu County in the Qin Dynasty, was good at using water conservancy knowledge to benefit the people. He respected water and followed the laws of water flow, and summed up the three-character mantra of water control: "Walk the beach deeply, build a weir low", and the eight-character mantra "Cut the corners when encountering the bay." "At the right time, I took heart" and also built the Dujiangyan Irrigation System that made Sichuan the "Land of Abundance". So Yu Qiuyu said: "I think the most exciting project in Chinese history is not the Great Wall, but Dujiangyan." Li Bing and Qin Shihuang's names were recorded in the annals of history.

Thinking of Shui En, we should repent. Lao Tzu said: "The wise enjoy the water, the benevolent enjoy the mountains." We should be grateful. Truly wise human beings should use the water resources that have been blessed to us like wise men. They should also have the feelings of a benevolent person, know how to utilize water resources, and also know how to cherish and care for water resources.

The middle and lower reaches of the Yellow River and the Yangtze River are the best areas for the birth of human beings

Chronology of the Pre-Xia Dynasty of Chinese Civilization

*The first stage: the invention of using fire and traveling through time Cloth Period

1. Peking Man (1 to 500,000 years ago)

Many animals can use simple stone tools and wooden tools, and many animals can walk upright or semi-upright, so whether Being able to use tools and walking upright are not the criteria for judging whether a person is human. I would like to point out that only those who hold up torches are considered human beings. The people before that who did not know how to use fire and could only make simple stone tools were not human beings, but apes or orangutans. The earliest known person to use fire is Peking Man. Previously, academic circles once called it Peking Man. This is wrong, because being able to use fire is a full-fledged human being. The reason is simple. All life forms neither dare nor know how to use fire. Only human beings have developed neuronal intelligence systems that can use fire and control fire. For details, please refer to the online version of the book "Uncovering the Highest Secret of Life".

The use of fire not only gives humans a powerful and invincible weapon, but also encourages humans to truly stand up, because only standing and walking can hold up torches. Equally important, the use of fire is a strong intellectual enlightenment for the user. Fire is both a signal and a reflection of self-confidence. It is the beating of fire that guides mankind towards civilization.

Humans who use fire need more cooperation and communication with each other, which further promotes the continuous improvement of human language and information capabilities, as well as the continuous improvement of intelligence level and survivability, resulting in a continuous increase in the population.

The first person to bravely pick up the torch should be a woman. Her action not only established humans as the king of creatures, but also established women’s leadership position in human society. Having women lead early humans helped the human group continue to expand because women had less sexual monopoly and less sexual exclusion than men.

2. The period of the invention of clothing (500,000 to 100,000 years ago)

At the same time, the long-term use of fire also prompted humans to become dependent on fire, and thus began to make and the wearing of clothing (straw, fur), and the gradual deterioration of body hair.

Based on the process of human beings inventing fire and clothing, we can deduce where the most likely place for human beings was born. First, since the earth's continents are mainly distributed in the northern hemisphere, humans are most likely to be born in the northern hemisphere. Second, the most conducive latitude for using fire and dressing up should be around 30 to 40 degrees north latitude. Here there are four distinct seasons, with cold and hot weather, so you need to use fire to keep warm and wear clothes to keep warm. In contrast, in the equatorial regions at low latitudes, the temperature is relatively high, so there is no need to use fire to keep warm, and there is no need to wear clothes; in the polar regions at high latitudes, the temperature is too cold, and the simple clothes originally made by humans cannot withstand such a cold climate. Third, North America is not known to be the place where humans were born. Fourth, although there have been ancient humanoid animals living in Africa, Africa is located in the equatorial region, with its northern end just reaching 30 degrees north latitude. The climate is not cold and the four seasons are not distinct. There is no need to use fire to keep warm, and there is no need to wear clothes. clothes, so Africa was not the first choice place for the birth of humans. Fifth, Europe is basically not within the range of 30 to 40 degrees north latitude, so Europe is not the place where humans were born. Sixth, according to the first five items, it can be seen that the most likely place for the birth of human beings is the area of ​​​​the Asian continent located at 30 to 40 degrees north latitude.

Furthermore, the Asian continent located at 30 to 40 degrees north latitude can be divided into three regions: eastern, central and western. First, the central region includes the Tianshan Mountains and the Qinghai-Tibet Plateau. It is far away from the ocean, has little precipitation, is too high in altitude, and has a poor living environment. Therefore, it is unlikely that humans were born in this area. Secondly, the western region includes the Iranian Plateau, Mesopotamia, and the Asia Minor Peninsula. Although the natural environment here is likely to give birth to humans; however, because the Iranian Plateau is relatively barren, the area of ​​the Mesopotamia and Asia Minor Peninsula is slightly smaller, so it is possible for humans to be born here. Sex is not high.

Third, the eastern region includes the middle and lower reaches of the Yangtze River and the Yellow River in China, as well as the Korean Peninsula and the Japanese Islands. Because the islands are relatively small and isolated, and lack room for survival, these places are not the place where humans were born.

China's middle and lower reaches of the Yangtze River and the middle and lower reaches of the Yellow River are located exactly between 30 and 40 degrees north latitude. Although this area is relatively rich in natural products (which is the basis for long-term stable survival), it is not like in the tropics. Food is readily available in the rainforest, so you have to use your brains to fight for it. In fact, this region has a vast area, moderate precipitation, distinct four seasons, rich terrain resources, developed water systems, including plains, plateaus, and many medium- and low-altitude mountains. There are a large number of natural caves in these mountains with an altitude of about 1,000 meters, which provided shelter for early human settlements. There are many pine trees and other flammable vegetation on the mountains. Natural wildfires will form when lightning strikes in dry years or seasons. This provides enough opportunities for apes to hold up torches and become humans. To sum up, it can be seen that the middle and lower reaches of the Yangtze River and the middle and lower reaches of the Yellow River in China are the best areas for the birth of human beings. It is no accident that people in Beijing first used fire 500,000 years ago. After humans were born in the middle and lower reaches of the Yangtze River and the middle and lower reaches of the Yellow River, they gradually migrated from here to other areas such as Eurasia and Africa.

They are all reposted, I hope you can read them all!
