Are there any churches that charge admission?

Many. The Saint Sophia Church in Harbin is an Orthodox church with no religious activities, so it can charge tickets openly. There are also many churches that sell tickets for tourists to visit because they are historical buildings, but if you declare to be a Christian, you can worship for free. St. Michael in the Catholic Diocese of Qingdao, Jinan Diocese, Pingyin Huzhuang, and Our Lady of Sheshan Church in Shanghai Diocese all charge a fee. They are the same as Buddhist temples. Ticket revenue is collected by the local tourism management agency. Don’t think of it as going into the pockets of the clergy. . Except for those false religious places that are selling sheep over dogs.
