Is there a rule that high-rise exterior walls in Hubei Province are not allowed to stick porcelain tiles?

The state does not expressly stipulate that high-rise buildings cannot be tiled.

If there are any local regulations in Hubei province, then ask the local construction department and quality supervision station clearly.

Generally speaking, there will be no such provision. If there is, it is also a local regulation. In order to prevent falling bricks from hurting people, the floor height should be clearly defined. Ultra-high-rise buildings do not advocate tiling, and there are indeed security risks.

I hope it works for you.
