The Huaqing Pool on the outskirts of Xi'an has been a hot spring bathing resort since ancient times and was also where the Xi'an Incident took place. During Emperor Xuanzong's reign in Tang Dynasty, it was a bathing place for the royal family and court ministers. Now, you can visit the royal pools of Tang Xuanzong and Yang Guifei, named Lotus Pool and Haitang Pool respectively. In 1936, the Xi'an Incident took place and changed China's destiny. In the southern part of the scenic spot, the “five halls” of Chiang Kai-shek’s old residential site were preserved intact, and the bullet marks of the fierce battle are still left on the walls.
