There is a natural cave in Taizi Rock, also known as Taizi Cave. It is said that he was the crown Prince of Jingle Kingdom, the place where Zhenwu practiced in his youth on Wudang Mountain. At the entrance of the Prince Cave, there is a stone hall imitating a wooden structure built in the Yuan Dynasty. It is exquisitely structured and elegant. In the main hall, there is also a stone carving of "Taizi Rock" dating back to the 27th year of the Zhiyuan period of the Yuan Dynasty, that is, 1290 AD, which serves as evidence for examining the age of the cave chamber's excavation. In the tenth year of Yongle in the Ming Dynasty, a brick and stone hall was built by imperial decree, housing a statue of Zhenwu when he was young. It has high cultural relic and artistic value.
