Master of Feng Shui: There is no backer behind the sofa. Can you use a rich tree as a backer?

The statement that the sofa must be against the wall is one-sided. The sofa against the wall is just a shape, and Feng Shui determines the shape of good or ill luck with reasonable qi.

If the position against the wall is dead, and Wang Naqi is a little farther away from the wall. Is it difficult to sit in a dead position? Sure, leave the wall and sit on it.
