Once upon a time, Linyi was the representative of Xi'an tourism. The most popular one was the world's eighth largest miracle terracotta warriors and horses. Its scale, burial pits and rich connotations have shocked the world. The same as the terracotta warriors and horses, Huaqing Pool, in the "Twelve Hours of Chang'an", the prototype of the hot spring palace that the saints and Yang Zhenren yearn for is Huaqing Pool, also known as Huaqing Palace. I don't know if I came to Linyi for the first time. I remember that every time I did 306 through Huaqing Pool, I would see the ruins in front of the scenic spot. Now I am here again. The original ruins have become a square, which is todays Datang Huaqing City. . Datang Huaqing City is actually a big square. It can also be understood as a tourist transfer station. The statue in the middle of the square is the form of the dance of Emperor Xuanzong and Yang Guifei!
