Introduction to the Sutra Collection Building: The Sutra Collection Building and Wangyue Tower are auxiliary buildings on both sides of Sanqing Pavilion, and are connected by verandas. The original collection of the Ming Dynasty edition of the Dao Zang in the Tibetan Scripture Building includes the "Zhengtong Dao Zang" compiled in the 10th year of Zhengtong (1445) and the "Wanli Continuing Dao Zang" compiled in the 35th year of Wanli, with a total of 5,485 volumes, which is a collection of Taoist classics. Every year on the seventh day of the sixth month of the lunar calendar, Baiyun Temple holds a sutra-drying meeting, where all the sutras are moved out and placed in a ventilated place to dry in the sun to prevent book beetles. What exists here is a copy. The original version was transferred to the Beijing Library (now the National Library) in 1950 for preservation.
