2. Look at the location of the house in the community.
3. Look for anything bad outside the window of the important space.
These cannot be changed, but they are also the most fundamental parts. If these are bad enough, then whatever you do indoors is just a cover-up.
The indoor part should be selected according to the situation. The specific situation is very complicated. For a common example, for example, you can see the bedroom door when you enter the door. This is a small shortcoming. However, if a screen or a large plant is erected in the case of a small house area, the pattern will not be smooth. This is to remove a small shortcoming and add a medium one. Sometimes in order to bypass the screen, turn the kitchen door first and then the toilet door. These are two supplements.
