Shenyang and Taixin have the problem of flying at low altitude every day.

1. According to what you said, you can know that the sky where you live is an air transportation line, and there must be many flights passing by every day.

2. It should be because when developers develop real estate, the relevant departments will have aviation height limit requirements for the real estate they develop. As long as it does not exceed its limited height, it is possible to develop commercial housing in this place.

3. Encountering such problems shows that the purpose of developers is not to consider the fundamental interests of owners.

4. If there is a relevant contract when purchasing a commercial house, you can complain to the relevant departments or safeguard the legitimate rights of the owners according to law.

5. For the problems promised by the developers, the owners can discuss them through the owners' committee and then coordinate with the developers. Problems that can be rectified should be rectified immediately, and owners who can't negotiate compensation with developers can't.

I hope my answer is helpful to you.
