Someone died and died for four days. What's the story?

Normal, there are customs everywhere, and it may be that they are buried only when the ecliptic is auspicious. Another possibility is the custom of mortuary. I have seen it, that is, when I went to Zhengzhou to play on National Day, I heard my mother say that someone died next door, and I began to cry. Later, nothing happened. As a result, it took several days to start the funeral. Hapi sings very well. I am also on business in Datong, Shanxi. I thought something happened that night. Then a friend of mine in Hebei said that someone died there and left it at home for a month, feeling that the dead in Shanxi, Henan Province were quite happy. But my home in Hubei is rather sad. . .
