Ming said that Li Zicheng died in Jiugong Mountain, and unofficial history said it was Luogong Mountain, but they all said that the body could not be identified. Another legend says that Li Zicheng fled for his life and became a monk. During the late Qing Dynasty and the Republic of China, a scholar went to Jiashan, Shimen to do textual research with the local old monks. Before the Qing Dynasty, a monk of unknown origin settled here, named "Feng Tianyu". This person has a Shaanxi accent (in line with Li Zicheng) and a meticulous appearance (in line with historical records). The tomb is a relic of the Republic of China, and it doesn't look like a forgery. In addition, Li Zicheng claimed to be General Fengtian Changyi, and later became king, while the monk claimed to be "Feng Tianyu", and the word "jade" was obviously a little more than "king"; Moreover, a few years after the monk settled down, another monk came. He is different from the former, but he is said to be a master and apprentice. He is respectful to the former and is suspected of breaking into the old army.
