Is the hardest museum to make an appointment in the country a temple?

Beijing's hardest-to-book Xihuang Temple Museum! The museum is only open on Saturdays and Sundays each week, and only 600 people are allowed to visit each day. If you want to visit, you need to grab a ticket 7 days in advance at 0 o'clock! Xihuang Temple was built in 1651 (the eighth year of Shunzhi in the Qing Dynasty), integrating Tibetan, Han, and Indian architectural arts, and is a gem of the architectural art of the Tibetan Buddhist royal temple. As one of the earliest established Tibetan Buddhist royal temples in Beijing in the early Qing Dynasty, Xihuang Temple is also the place where the Dalai and Panchen Lamas stayed in Beijing, and it has a relatively important historical value for studying Tibetan Buddhism in the Qing Dynasty. The museum is now also a senior Buddhist college of the Chinese Tibetan language system.
