Nobody in the mahjong room changes Feng Shui every day.

Feng shui is divided into two parts: disorder of head and regulation of qi. To put it simply, Luan Tou is an environmental feng shui, and Li Qi is a flying star feng shui. Luan head is very simple, a qualified feng shui master can see the good or ill luck of Luan head at a glance; Adjusting the air requires the Feng Shui master to fly with nine planets, and gossip counts as a house, which consumes the energy of the Feng Shui master, not just by opening his mouth. What you said is related to regulating qi, so it's not easy.
