Weird, residential feng shui. What should I do if I saw something dirty when I was a child?

Don't take what happened when you were a child too seriously. As for theaters, cinemas and other places where people come and go, there is indeed a suspicion that the gas field is not good, but since it has been rebuilt, it will be fine. Besides, even a ghost can do no harm. People and ghosts are different ways and generally do not interfere with each other. If they are weak, they may be afraid. I can only draw this conclusion from your description. You can trust me privately if you have any questions.
