I've heard a few things about the Fourth Church. For example, it is an imitation of the Soviet-style building, in order to have more light, it is not due south and north, but even so, inside the building is still very gloomy, or not very good lighting; another example, it has a large terrace on the roof, the terrace will have some people in the weekend there to learn to dance, and reach out to pick acacia flowers, but there are some rooms on the top floor is locked for a long time; also for example: it is said that the Cultural Revolution. There may have been trials of some people, or some people were wronged there.
Before 2000, HBU had not been tearing down the walls to make it green, and the location where the Fourth Church was located was, at that time, relatively remote, and not too many people went to classes there. Many people who attended HBU should have gone there to get books when they enrolled, because the bookstore was done, and it seems that the College of Fine Arts was also located there.
The reputation of the "Ghost House" is well known, but it seems that I have never heard of any other, or it is all interpretation!
After all, we want people to be healthy, healthy in their hearts, don't you think?
