Laomu Cave, Mount Song, Dengfeng, Henan.

The cave is divided into east and west courtyards, with more than 100 rooms. The two courtyards are 188 meters long from east to west, 64 meters wide from north to south, and cover an area of about 12,032 square meters. The east courtyard is the main courtyard, with three courtyards from the gate to the rear hall. The main buildings are the Wujilaojun Hall, Wujilaomu Hall, etc. The Wujilaojun Hall is located at the end of the east courtyard. It was built in the late Qing Dynasty, with three rooms wide and five rafters deep, and a large hard mountain with yellow glazed tiles on the front eaves. There are two symmetrical coiled dragon wooden columns in the hall. The Qianfo Hall is located on the east side of the Wujilaomu Hall, with three rooms wide and five rafters deep, and a hard mountain with gray tube tiles on the front eaves, lattice doors and windows, and square stone columns on the front eaves. There are more than 20 steles from the Qing Dynasty to the Republic of China in Laojun Cave, most of which are about renovation, donation, and records, reflecting the development of Taoism among ancient people to a certain extent.
