Lintong Iron Furnace is a famous master of Feng Shui.

Xi is a famous ancient capital of China. Ten dynasties, including Western Zhou Dynasty, Qin Dynasty, Western Han Dynasty, Former Zhao Dynasty, Former Qin Dynasty, Later Qin Dynasty, Western Wei Dynasty, Northern Zhou Dynasty, Sui Dynasty and Tang Dynasty, have established their capitals in Xi 'an area for more than 0/000 years, making it the longest imperial capital in China history.

Xi 'an should become the imperial city for two reasons:

First, Xi 'an is the leader of the Central Plains, with superior geographical position and control over the world. According to Feng Shui, Long Mai in the Central Plains originated from Guanzhong. So Chang 'an stands on the top of the dragon, overlooking the Central Plains. Moreover, Chang 'an is located in the upper reaches of the Yellow River, which has the geographical advantage of "six rivers in the upper reaches".

Regarding Chang 'an as the dragon head of the Central Plains, its legend goes back to ancient times. According to Li Daoyuan's Notes on Water Classics, there was a black dragon in the Qin Dynasty, which went out of Nanshan and drank Wei water. The route it traveled later became a mountain range, which was more than 60 miles long, with its head facing Weishui and its tail reaching Fan Chuan. During the Han Dynasty, Xiao He built Weiyang Palace and cut dragons at the top of the mountain to camp it. The head is 20 feet high and the tail gradually decreases to five or six feet. It can be seen that the so-called Longshou Mountain is located in Weiyang Palace in Xi 'an.

Second, Chang 'an carries water according to the mountain, and wins according to the shape of the world. The ancients had long believed that Chang 'an was the best place in the world, and it should be the imperial capital. In 264 BC, Xun Kuang came to Xianyang, and Qin fought with Zhao Dou. The Prime Minister asked him, "How do you feel about entering Qin?" Xun Kuang replied: "The situation in Qin is dangerous, with beautiful mountains and rivers and rich products. It is also a victory. "

In 202 BC, after Emperor Gaozu pacified the world, he thought Luoyang had a legacy of Zhou family and planned to build its capital here. Later, a Qi garrison named Lou Jing sought audience with Liu Bang and urged him to enter the customs. Liu asked Sean, a counselor, and Sean agreed with Lou Jing. Therefore, Liu Bangcai made Guanzhong his capital.
