Ticket office introduction: To the east of Nanfeng Gate is the Crown Prince's Palace. The gate of the palace is called Jiali Gate, and the palace names are Huihe Hall and Qingfu Hall. Emperor Taizong of the Tang Dynasty and Crown Prince Li Zhi both lived here. Later, they thought it was remote and gave it to the eminent monk Xuanzang as a place to translate scriptures. Xuanzang lived here for five years. After the Anshi Rebellion, the place gradually became deserted. Now, no tiles of the original buildings of Yuhua Palace remain, leaving only three grottoes, which the locals call the "Main Palace", "East Palace" and "West Palace". The "Main Palace" is located 1 kilometer inside the Phoenix Valley. The grotto originally enshrined the statue of Sakyamuni built by Xuanzang and a stone Buddha's footprint, which is 37 centimeters long and is now collected in the Chinese History Museum.
