About 3 kilometers south of Xinjin County, Laojun Mountain, also known as Tianshe Mountain and Choujing Mountain, is a famous Taoist place in western Sichuan and the fourth rule in the "Twenty-Four Rule" of Zhang Daoling's "Five Dows of Rice Road" in the Han Dynasty - "Choujing Mountain". The location of "Jingzhi" is said to be the place of Lao Tzu's retreat. The mountain is famous for its Taoist architecture and the grand Laojun temple fair. Most of the buildings that tourists see here today were rebuilt later. The main buildings are Tianci Palace, Lingzu Building, Hunyuan Palace, Bagua Pavilion Sanqing Palace and Qizhen Palace. The 15th day of the second lunar month of the lunar calendar is the birthday of Lao Tzu, the ancestor of Taoism (that is, Taishang Laojun). On this day, the whole mountain is full of tourists who come to pray for blessings, and there are people everywhere.
