What does it mean to close the mountain when people die?

It is a custom to close the mountain and go to the grave when people die! People must be buried on the third day after death (called closing mountains to kill people), and then go to the grave on the sixth or seventh day after death! Going to the grave on the sixth day (the sixth day after death) is called "the first seven", which means that the first seven days are deducted every seven days, that is, going to the grave every six days, a total of five sevens, that is, going to the grave five times a month is complete! This answer is for reference only. Don't be blindly superstitious.
