The developer said that you can smash the wall, but the property is not allowed. What should I do?

If it is really not a load-bearing wall, the easiest way is to find the leader of the property company and insert a red envelope.

If it is a load-bearing wall, restore it to its original state quickly. You should communicate with the property in advance to avoid disputes.

Let them send someone (usually the decoration inspection master of the engineering department) to confirm that the house decoration is good for people. If it's really load-bearing, don't you worry about living at night?
