The origin of the New Year
As the saying goes: "If you have money or don't have money, get together to celebrate the New Year." For thousands of years, the Chinese nation's custom of "Celebrating the New Year" has been continues.
How did the Chinese New Year come into being?
"Nian" is not a festival, but an animal. Legend has it that in ancient times, this animal was very ferocious. They gather together, and when they go out, there are thousands or hundreds of them. Every winter, they come out to look for food. Wherever they go, people and various animals will suffer. It is said that a group can eat hundreds of tigers, leopards, bears and dozens of people once a year. As soon as winter comes, the people have to concentrate their efforts to fight against Nian. It is not until spring comes that the flowers bloom and the temperature rises, and Nian disappears without a trace. In order to protect themselves from the harm of the New Year, whenever winter comes, people have to call back their relatives who have gone out to hunt in advance and reunite them together. They all live in groups in large caves, with up to a hundred people in each cave. In the process, people gradually accumulated some experience and found that although Nian is ferocious and cruel, it is most afraid of fire and will run away as soon as it sees the light of fire. Therefore, once people find out that the New Year group is invading, they quickly light the torches that have been prepared, hold weapons and shout in support until all the New Year group are driven away. The next day, people living in various caves got up early and said hello to each other. If everyone is safe and sound, bow to each other and express congratulations. Children also have to kneel down and kowtow to the adults to thank them for being the younger generation. After that, the custom of bowing and kowtowing to each other to pay New Year greetings gradually formed.
After the Yellow Emperor unified the tribes, he led the people to resist various natural disasters. In order to completely eliminate the huge threat of Nian to people, Huangdi discussed what measures to take with ministers such as Yinglong and Limu. Some people advocate relocation, while others advocate hunting and killing. Finally, according to Huangdi's opinion, everyone agreed to take the method of complete elimination. So, when the severe winter came, each tribe organized a team of a hundred people to hunt and kill the Nian. After more than ten severe winters of continuous hunting, the Nian became less and less, and the Nian in groups could no longer be seen.
However, Nian is not willing to become extinct like this. Legend has it that it turns into a nine-headed bird. On the eve of the New Year's Eve, it flies out and uses its nose to smell the odors wafting out of every house. The smell of fragrant meat makes bloody saliva flow from your mouth. Anyone whose yard this snowy saliva falls into will be in bad luck the next year. Later, people discovered that the nine-headed bird was most afraid of the smell of burning cypress leaves. So every winter, people collect cypress leaves. On the night of the 30th, every household burns cypress leaves. The smoke rises so thickly that the nine-headed bird never dares to fly out again. Since then, burning incense has become a custom every New Year’s Eve and has been passed down to this day.
The concepts of Spring Festival and Nian originally came from agriculture. In ancient times, people called the growth cycle of grains "Nian", "Shuowen." "Hebu": "The year means that the grain is ripe:. In the Xia and Shang dynasties, the lunar calendar was produced, using the moon's waxing and waning cycle as the month, and the year was divided into twelve months. The day when the moon is not visible is the new day of each month, and the first day of the first lunar month is the new day. Zushi is called the beginning of the year, which is the beginning of the year, also called the year. The name of the year began in the Zhou Dynasty, and was officially fixed in the Western Han Dynasty, and continues to this day. However, in ancient times, the first day of the first lunar month was called. It was regarded as "New Year's Day" until the victory of the Revolution of 1911 in modern China. In order to adapt to the farming season and facilitate statistics, the Nanjing Provisional Government stipulated the use of the lunar calendar among the people, and implemented the Gregorian calendar in government agencies, factories, mines, schools and groups, with the first day of the first month of the Gregorian calendar as the day. New Year's Day, the first day of the first month of the lunar calendar, is called the Spring Festival.
The arrival of the Spring Festival means that spring is coming, everything is revived and the vegetation is renewed, and a new round of sowing and harvesting seasons is about to begin. In the long cold winter, we have long been looking forward to the days when spring will bloom. When the New Year arrives, we will naturally welcome this festival with joy, singing and dancing.
On September 27, 1949, the People’s Republic of China was founded. At the first plenary session of the Political Consultative Conference, it was adopted that the first day of the first lunar month of the Gregorian calendar be designated as New Year's Day, commonly known as the Gregorian calendar year. It must be the "Spring Festival", commonly known as the lunar year.
The Spring Festival in the traditional sense refers to the twelfth lunar month on the eighth day of the twelfth lunar month or the twelfth lunar month on the twenty-third day of the twelfth lunar month, until the fifteenth day of the first lunar month, including New Year's Eve and the first lunar month. The first is the climax. During the traditional festival of the Spring Festival, the Han people and most ethnic minorities in my country hold various celebration activities. Most of these activities are centered on worshiping gods and Buddhas, paying homage to ancestors, removing the old and bringing in the new, welcoming the new year, and praying for a good harvest. Main content. The activities are rich and colorful, with strong national characteristics.
One of the legends of the Spring Festival: Staying up until the end of the year
Staying up late means not sleeping on the last night of the new year. The custom of staying up late to welcome the new year is also called staying up late on New Year's Eve, commonly known as "staying up late". There is an interesting story circulating among the people about the origin of this custom:
In ancient times, there was a ferocious spirit. Monsters live scattered in deep mountains and dense forests. People call them "Nian". They have a ferocious appearance and a ferocious nature. They specialize in eating birds, animals, and scale insects. They change their taste every day, ranging from kowtowing insects to large living people. It makes people talk about "Nian" in disgrace. Later, people gradually grasped the activity pattern of "Nian". It goes to crowded places to taste fresh food every three hundred and sixty-five days, and it appears at the same time. After dark, when the rooster crows and dawn breaks, they return to the mountains and forests.
After calculating the date of the "year", the people regard this terrible night as the gateway for evil. It is called "New Year's Eve", and they have come up with a whole set of ways to celebrate the New Year: every night on this day, every household prepares dinner in advance, turns off the fire and cleans the stove, then fastens all the chicken pens and cattle pens, and cleans the house. The front and back doors are sealed, and the "New Year's Eve dinner" is eaten indoors. Because this dinner has an unlucky meaning, it is very sumptuous. In addition to having the whole family eat together to express harmony and reunion, it is also necessary to Before eating, they offer sacrifices to their ancestors and pray for their blessings to spend the night safely. After dinner, no one dares to sleep, and they sit together to chat and strengthen their courage. Gradually, we formed the habit of staying up late on New Year's Eve.
The custom of keeping the year old arose in the Northern and Southern Dynasties, and many literati in the Liang Dynasty wrote poems and essays about keeping the year old. "One night lasts two years, and the fifth watch divides two years." People light candles or oil lamps and keep vigil all night, which symbolizes driving away all evil plagues and looking forward to good luck in the new year. This custom has been passed down to this day.
Spring Festival Legend 2: Wannian created the calendar
According to legend, in ancient times, there was a young man named Wannian who had an idea when he saw that the seasons were very chaotic at that time. The plan to set the seasons accurately. But he couldn't find a way to calculate time. One day, when he was tired from going up the mountain to chop firewood, he sat under the shade of a tree to rest. The movement of the tree shadows inspired him. He designed a dial to measure the sun's shadow and measure the time of the day. Later, the dripping spring on the cliff inspired him, and he made a five-layer clepsydra to calculate time.
As time went by, he discovered that every three hundred and sixty days, the four seasons cycled around again, and the length of the days repeated themselves.
The king at that time was named Zu Yi, and he was often distressed by the unpredictable weather conditions. After Wan Nian found out, he took the sundial and the clepsydra to see the emperor and explained to Zu Yi the principles of the movement of the sun and the moon. After Zu Yi heard this, Long Yan was overjoyed and felt that it made sense. So he left ten thousand years to build the Sun and Moon Pavilion in front of the Temple of Heaven, and built the sundial platform and leaky pot pavilion. He also hopes to accurately measure the laws of the sun and the moon, calculate the accurate morning and evening times, and create a calendar to benefit the people of the world.
Once, Zu Yi went to learn about the progress of the ten thousand year test calendar. When he climbed up to the Temple of the Sun and Moon, he saw a poem carved on the stone wall beside the Temple of Heaven:
The sun rises and sets three hundred and six times, starting all over again.
There are four seasons of vegetation and trees, and there are twelve circles in one year.
Knowing that the Wannian Calendar had been established, I personally went to the Sun Moon Pavilion to visit Wannian. Wan Nian pointed to the sky and said to Zu Yi: "Now is the end of the twelve months. The old year is over and the new year has begun. Please pray to the king to set a festival." Zu Yi said: "Spring is the beginning of the year, so let's call it the Spring Festival." It is said that this is the origin of the Spring Festival.
Winter passed and spring came, year after year, ten thousand years after long-term observation and careful calculation, an accurate solar calendar was formulated. When he presented the solar calendar to his successor, his face was full of silver. Must. The monarch was deeply moved. In order to commemorate Wannian's achievements, he named the solar calendar "Wannian Calendar" and named Wannian the sun, moon and longevity star. Later, people hung pictures of longevity stars during the Chinese New Year, which is said to commemorate the ten thousand years of high moral character.
Spring Festival Legend Three: Pasting Spring Festival Couplets and the Door God
It is said that the custom of pasting Spring Festival couplets began in the Hou Shu period more than a thousand years ago, which is evidenced by history. In addition, according to the records of "Jade Candle Collection", "Yanjing Chronicles" and other works, the original form of Spring Festival couplets is what people call "Peach Talisman".
In ancient Chinese mythology, it is said that there is a world of ghosts. There is a mountain in it. There is a large peach tree covering three thousand miles on the mountain, and there is a golden rooster on the treetop. Whenever the golden rooster crows in the morning, the ghosts who wandered out at night will rush back to the ghost land. The gate of the ghost realm is located in the northeast of the peach tree. There are two gods and men named Shen Tu and Yu Lei standing by the gate. If a ghost does something harmful to nature at night, Shen Tu and Yu Lei will immediately discover it and catch it, tie it up with a rope made of awning reed, and send it to feed the tiger. Therefore, all the ghosts in the world are afraid of Shen Tu and Yu Lei. So people carved their images out of peach wood and placed them at their doorsteps to avoid evil and harm. Later, people simply engraved the names of Shen Tu and Yu Lei on peach boards, thinking that doing so could also suppress evil and eliminate evil. This kind of peach wood board was later called "Peach Run".
In the Song Dynasty, people began to write couplets on peach boards, one without losing the meaning of peach wood to suppress evil, the other to express their good wishes, and the third to decorate the door for beauty. Couplets are also written on red paper, which symbolizes joy and auspiciousness, and are pasted on both sides of doors and windows during the New Year to express people's best wishes for good luck in the coming year.
In order to pray for the happiness, longevity and health of the family, people in some places still retain the habit of sticking to the door god. It is said that if two door gods are posted on the door, all monsters and ghosts will be intimidated. Among the people, the door god is a symbol of righteousness and force. The ancients believed that people with strange looks often have magical talents and extraordinary abilities. They are upright and kind-hearted, and it is their nature and responsibility to catch ghosts and demons. Zhong Kui, the ghost-hunting master that people admire, has such a strange appearance. Therefore, the folk door gods always have angry eyes and ferocious looks, holding various traditional weapons in their hands, ready to fight any ghosts who dare to come to the door. Since the doors of Chinese houses usually have two doors opening opposite each other, door gods always come in pairs.
After the Tang Dynasty, in addition to the previous two generals Shen Tu and Yu Lei, people also regarded the two Tang Dynasty generals Qin Shubao and Yuchi Gong as door gods. According to legend, Emperor Taizong of the Tang Dynasty was ill and heard ghosts calling outside his door, making him restless all night. So he asked the two generals to stand guard by the door with weapons in hand, and the next night there were no more ghosts to disturb him. Later, Emperor Taizong of the Tang Dynasty asked people to draw the images of these two generals and paste them on the door. This custom began to spread among the people.
A simple summary is: Nian is a monster. On New Year's Eve, he will come out to destroy crops, bully people, and eat children. In order to destroy Nian, people will set off firecrackers to scare Nian away.
