What is the saying that people die for a hundred days?

One hundred days after death is called a hundred-day grave.

This is another grave besides Santian grave, Sanqi grave and Wuqi grave after his death.

On the centennial grave, we will burn paper and offer offerings, and those who have daughters will plant a tree, saying it is a "cash cow". Different regions have different ways of offering sacrifices. Some people in the south set off firecrackers on this day. There are not so many sayings in the north. Generally speaking, they just burn paper and incense, place offerings, kowtow and offer flowers. Dai Xiao can burn black veil (wearing 100 days is very filial, but it is almost the same as 1 month), and you can get a haircut on this day.
