1. First of all, Building No.2 is the most special, because Building No.2 is located in the first row of the community, without any buildings and shelter, and facing the sun, which will not lead to darkness and no sunshine in the room.
2. Besides, it is forbidden to whistle in the street next to Building 2 after 6: 00 p.m., so there is no need to worry that there will be whistling in the street at night to affect the rest, so the environmental conditions are the best.
