Do I need to make an appointment to go to Beijing Baiyun Temple?

Official website, a local treasure of Beijing, inquired that visitors to Beijing Baiyunguan must book online and purchase tickets on site. Beijing Baiyunguan is located in Baiyunguan Street outside Xibianmen, Xicheng District, Beijing. The building is divided into three roads, namely middle road, east road, west road and backyard. It has a large scale and enjoys the reputation of "the first jungle of truth".
