Feng shui man sleeps and exhales.

In superstitious terms, it is this man who is blowing mud. Why blow dirty water? That is, it used to be buried in the earth, and it still has to be buried in the earth. He was afraid of being buried, so he blew dirt with his mouth, which meant that the man was going to die. Many people say this phenomenon is ingenious. Actually, I don't believe it either Most of them are caused by the airtight nose and difficulty in breathing, which can only be caused by breathing through the mouth.
