According to feng shui, it is not good to see the sink when you enter the door. The sink is a dirty and humid place, and the living room is a place for people to rest and relax. Therefore, it is not appropriate to put the sink in the living room, especially opposite the entrance of the living room.
However, this is only a view of Feng Shui, and it cannot be completely superstitious. In real life, we need to make judgments and decisions according to the actual situation.
