Does putting hexagonal vases in the living room affect Feng Shui?

It is not good to put hexagonal vases in the living room. It is best to put a round vase in the northwest corner of the bedroom. Northwest hexagrams, that is, the male master, put a round vase in the northwest corner, just to let the vase surround the male master, and the male master's habits will be tamed unconsciously. Conversely, if you put something sharp in the northwest corner, it will make the man look fierce and overbearing.
