After the unification of China, Qin Shihuang thought that Xianyang was crowded and the former imperial palace was small, so he recruited 700,000 torturers and built a palace in Xi 'an and Xi 'afang Village, south of Weishui, and then formed a huge complex, namely Afang Palace.

Epang Palace is famous for its grandeur. Du Mu, a famous poet in the Tang Dynasty, wrote in "A Fang Gong Fu": Shu, A Fang Chu. Overpressure exceeds 300 miles, isolated from the sun. Five steps to the first floor, ten steps to a pavilion; The corridor is waist-high, with high eaves and teeth, each holding its own terrain and intrigue. There is a lot of water in the hive. I didn't know it had tens of millions. According to historical records, only the front hall was built, with 500 steps from east to west and 50 feet from north to south, with a seating capacity of 10,000 people on the top and a five-foot flag on the bottom. And Zhou Chi is a pavilion road, from your highness to Nanshan, and its scale seems incredible.
