The shape of the window is regular. Because there is a cross beam blocking the inner window sash, it can't be opened. After that, the sash moves down, and the bright glass at the bottom is split in two, making the sash in the middle big and the bright glass at the top and bottom narrow. It depends on where your wall is. If it's a bedroom, don't open two windows. It can be said that in addition to the living room, try not to open two windows in other spaces, because Feng Shui is also compiled according to ergonomics. If you open two windows, the indoor temperature will rise in summer and cool down in winter, which is not suitable for people's health! If the length of the bedroom exceeds 16 meters, it is necessary to open two or even three windows, but this is almost impossible!
