What does the Death Star mean?

What does fortune telling mean by writing a door star?

It should be a door star, not a door star. Sangmenxing refers to the twelve-god Sangmenshen before 12 years old, who always faces the white tiger and meets the public. Therefore, when Sangmen is in Shougong, Parents Palace and Tianzhai Palace, there may be photos of mourning. If time flies, it will strengthen the meaning of mourning.

It can be understood as the death of a family member.
