What does it mean to not put green plants in the northwest of the living room?

In the living room feng shui, the living room has a wealth position, and the wealth position of the living room is generally on the diagonal line of the living room door, and the direction of the wealth position appears on the pillars, recesses, and windows, which will lead to the leakage of wealth. In order to prevent the leakage of wealth, you can place some plants, wine cabinets, partitions, and cabinet cabinets in these directions to block it, so as to ensure that the money in the living room does not leak out.
