Feng Shui is the same as fortune-telling. If you believe in the existence of Feng Shui, then you need to look at Feng Shui. Feng shui aims at the harmony between heaven, earth and man, that is, the unity of heaven, earth and man; that is, the harmony and unity between man and nature; the harmony and unity between man and the biological world. Houses generally do not have a back door, which can leak money. If the door is opposite to the main door, it also violates the first evil of Yangzhai. It has adverse effects on health, wealth and other aspects.
