Avoid placing beams and building safety doors in the yellow calendar. Can you install windows like this?

I can't. Because the Gregorian calendar says that the upper beam is not only the upper beam, but also all the construction work in the family, such as cutting walls, laying bricks, tiling, installing doors and windows and locking. In other words, no construction can be carried out. In addition, families with pregnant women and people with serious diseases should not build houses or houses.
