Hello, I'm a volunteer at Longquan Temple in Fenghuangling. Anyone can stay there at night as long as they have valid identity documents. Millennium Temple is quiet and peaceful, which is a rare place to cultivate one's mind and cultivate one's nature in Beijing. There is a charity foundation and a clothing-plus-clothing project on the mountain to send donated clothes to poor and cold areas. If you have a chance to see it, please feel free.
