What is the origin of Xianyang's name? In ancient China, people thought that the mountains in the south and the water in the north were the sun. At that time, Xianyang was located in the north of Weishui, nine miles away from Shan Zhinan, with clear mountains and rivers, so it was called "Xianyang". During the political reform, in order to expand the influence of Qin, Xianyang was built and moved here. After 100 years, Xianyang has been the capital of Qin.
During the Qin Dynasty, Xianyang was the largest city in Guanzhong. After the peasant uprising broke out at the end of Qin Dynasty, the Qin Dynasty was overthrown. After Xiang Yu occupied Guanzhong, he slaughtered the descendants of Won and set fire to Xianyang, headed by Epang Palace. According to historical records, the fire lasted for more than three months. After more than three months, Xianyang was basically in ruins. What is preserved is Chang 'an, a small town near Xianyang. At that time, Chang 'an belonged to a town under Xianyang, which was very close to Xianyang.
After Emperor Gaozu Liu Bang decided to move the capital to Guanzhong, the first question before him was where the capital was built. Finally, Liu Bang and others chose Chang 'an, a small town under Xianyang. Liu Bang ordered Xiao He to preside over the construction of a brand-new Chang 'an City. On the basis of the small town Chang 'an, Xiao He began to build a new capital Chang 'an on a large scale. Because the original Xianyang and the original Chang 'an are very close, when Xiao He was building a new Chang 'an, a part of the original Xianyang was also included in the new Chang 'an. In other words, part of Xianyang has also become Chang 'an. Or it can be said that Chang 'an is the result of Xianyang's translation and expansion. We can also understand that ancient Xianyang and ancient Chang 'an overlap to some extent.
Liu bang didn't waste the rest of Xianyang. Liu Bang transferred the rest of the original Xianyang to the original Xianyang and became a part of the location of the imperial tomb in the Western Han Dynasty. Later, the prosperous "Five Tombs" were formed in the original area of Xianyang, which continued the prosperity of Xianyang in the past.
After the Han Dynasty, the dynasties that built Guanzhong as their capital basically built new capitals on the basis of Chang 'an, and there was no need to restore the former Xianyang City. In fact, to continue the glory of Chang 'an is to continue the glory of Xianyang. After the Tang Dynasty, because the land in Guanzhong was gradually barren and the southern economy developed and prospered, Guanzhong's position became more and more embarrassing, which made it difficult to meet the needs of national development. Luoyang, the eastern capital, was built in the Sui and Tang Dynasties to adapt to the changes of the times. After the Tang Dynasty, no dynasty had its capital in Guanzhong, and no dynasty had its capital in Chang 'an, let alone rebuild Xianyang.
