There are two versions.
First of all, the inner court used to be an execution ground, and the natural feng shui was not good, which made it impossible to build the building. It is said that this place is haunted. Who has seen it?
Second, the roof of the building was crooked from the beginning, which made the top floor unable to be covered and unbearable. It is said that only drawings can prove this.
The first one has a legend.
It is said that decades ago, it was still the age of watching plays. One day in a theater garden, grandpa was watching the play with his grandson in his arms. Grandpa liked watching the play best. But that day, I don't know why, his favorite grandson always cried and kept going. Finally, grandpa had no choice but to hold his grandson in his arms for fear of crying him to death. Out of the theater gate, grandpa asked his grandson why he always cried. Grandson told him that because I was afraid, I saw those people had no heads. Just after they walked not far away. A fire broke out in the theater. None of the people inside escaped and died inside.
Why didn't anyone escape? Because there was a problem with the building in the past, it was not like this. Both sides can be opened or pushed out. At that time, the door had to be pulled so hard that everyone blocked the door and squeezed out. In the end, none of them came out.
Consider it the second reason. Take the first one as a joke.
