Introduction to Tianjing Palace: Woyang Tianjing Palace, commonly known as Laozi Temple, also known as Zhongtaiqing Palace, is located in the north of Woyang County, two miles away from Gushui (now called Wujia River) in the south, and pillowed on Longshan Mountain in the north. Surrounded by water, the environment is quiet. Since 1989, after many investigations and demonstrations by experts and scholars at home and abroad, it has been confirmed that this is the birthplace of Lao Tzu and the former site of Tianjing Palace, so Tianjing Palace was rebuilt.
