Backyards of rural houses with backyards can be opened. However, there is a certain emphasis on opening the backyard, mainly as follows: first, the door opened in the backyard should be narrow, that is, you can't use double doors, you can only use single doors.
Second, open a single door, close it when no one comes in or out, and don't open it often. Old people in rural areas say that it is the intention to gather wealth, but in fact, anti-theft is the original intention.
