Geomantic terminology of tuyere
Feng Shui is most taboo about "being dead", "holding your breath" and "being discouraged".
The tuyere will cause "air leakage" and "deflation". The ancient geomantic omen in China thought that "the wind disperses the qi" and "attracts the wind and causes trouble", so it required "hiding the wind and gathering the qi". Hiding the wind is avoiding the phoenix. The tuyere is the source of trouble. Why? This is because the wind speed is too large, the gas field changes too much, and it is difficult for people to adapt, and it is difficult to establish a balance between the human body field and the environmental field, so people will feel uncomfortable and even get sick because of losing their breath.
No wind will cause "death" and "suffocation". Human body and family life emit a lot of waste gas every day. If the ventilation is poor, the indoor and outdoor air exchange is difficult, and the exhaust gas will stay indoors, causing its own pollution.
