First, it is best not to face the door on the sofa, which may have an impact on people's spirit and body.
Suggestion: You can erect screens or plants at the door.
Second, I found that there seems to be no toilet in the layout of the landlord? Or is the toilet independent outside?
Third, it's best to change the God of Wealth tree beside the desk regularly or take it to the window for lighting.
Fourth, sofas, hanging pictures and decorations should be imposing, so that foreign guests can raise their heads rather than bow their heads.
You can't see anything else just by looking at the layout. It's just that the center is a little empty. It's best to put a big bonsai or something to show a vitality.
