Why do people write on a brick after death?

That's a monument.

The significance of erecting a monument is mainly to guide worshippers, but also to express respect and nostalgia for ancestors. Some involve Feng Shui theory, and they have faith, but they have no faith.

The origin of the monument: the graves of bereaved families can be remembered clearly for one or two generations, but not after three generations, especially after migration and war. How to solve it, people have come up with many ways. At first, people buried the dead. Inspired by the wooden stakes used to maintain the coffin rope, they inserted wooden stakes and bamboo poles in front of the tomb and tied fibrous things (paper or silk, etc.) ) to indicate the date and time of birth and death of the deceased, which is called "Ming Jing" (or "Ming Jing"). But it is easy to be damaged, so people try to find another way: the rich use stone pillars instead of wooden pillars, and engrave the name, birth time and official rank of the deceased on the stone pillars.
