Please have a look at those who know Feng Shui. Number 5 is the location of the underpass. What should I put?

If the spaciousness of No.5 doesn't affect walking, it is suggested to put a few chest-high potted plants below, and use short potted plants for waste. Because you didn't provide the direction of the house, the specific question can't be answered. Second, the third bedroom is a little lower than the living room and does not need to be remodeled. You got more gasoline, which is a good thing.
