Why is the handle ceiling in the bedroom not good?

It should be a bit like the top of the hilt, which means bad in feng shui.

The material and form of the room ceiling are designed and built according to the requirements of users. If the user doesn't like this form, he can ask to change it to his favorite form. There is no good or bad ceiling form, only he likes it or not. If users pay attention to feng shui, can they ask someone with this knowledge to confirm it?
