Will you floor the building?

People who live in commercial and residential buildings in cities now usually have wooden floors in their rooms. If you spread the floor on the wooden floor, it is generally no problem to spread the floor because there is a certain height interval between the wooden floor and the ground. If you spread the floor directly on the concrete floor, you should pay attention. First, the bottom should be thicker, or some summer sleeping mats should be laid, because the cement floor can transfer heat quickly, and it is easy for people to catch cold when sleeping on the non-mud floor. Koreans and Japanese lay the floor.
