The house is on the east side of the mountain. If I want to open windows on the east side of the mountain, will it affect Feng Shui? urgent!

In ancient times, gables were firewalls to prevent chain fires between houses, so gables generally did not have windows in ancient times. Today, fire protection regulations also stipulate that no windows should be opened on gables within 6 meters. If windows are to be opened, fire-resistant windows are required. Therefore, if the landlord wants to know whether the window should be opened, he can first consider whether there are such fire protection requirements. If not, he can consider opening it. As for whether this window is in a good sitting direction and whether it receives good air, it is necessary to provide accurate building plan and orientation before it can be determined. No hasty judgment here.
