Introduction to Haiyunguan: The original site of Haiyunguan was built in the Jin Dynasty and is the birthplace of Taoism in Heilongjiang. In the early years, the number of Taoist priests who came here to practice Taoism increased day by day, and Songfeng Mountain was flourishing for a time. In the third year of Xuantong, officials from Binzhou Prefecture came to the mountain and erected two stone tablets for Haiyun Temple to commemorate the Taoist priests who founded the mountain.
