What do the scarlet letter and black characters on the tombstone mean?

Names painted in red and black on tombstones are mainly used to distinguish the dead from the living.

Their names are scrawled in red on the tombstones of the two living old people.

An old man died, his name was painted black, and the name of the living old man was painted red.

Both old people have passed away, so their names are written in black.

At the same time, if the names of relatives and friends of the children of the elderly appear on the tombstone, they are also painted red.

Black expresses a kind of mourning, and red symbolizes fresh life.
