because the rear is yang and the fire and water belong to yin, it is not suitable. The rear is the backing surface of the whole house, which is the male owner of the house. If the stove is installed here, it will be harmful to the male owner's health, and the main culprit is blood pressure or cardiovascular and cerebrovascular problems; If the male host is still young and strong, the host is grumpy and easily gets angry; In addition, this situation also has an impact on the family. After living for a long time, there are cases where a son feels rebellious against his father, and the father and son are often angry. If this side installs a water tank or faucet, its efficacy is almost the same as that of "shower head water", and elderly men need to prevent stroke or encephalopathy or nephropathy. This is the most important taboo in home feng shui, where the position of fire and water is placed.
