Update 1:

Is it the same thing?

"Epitaph according to "Modern Chinese Dictionary" explains: "Epitaph: placed in a tomb with the deceased inscribed on it Stone carvings of life events. Also refers to the words on the epitaph. Some have inscriptions ending in rhymes, also called epitaphs. "But many people misuse this term. They don't know that epitaphs are placed inside tombs and can't be seen by people outside the tomb. They mistakenly call tombstones and inscriptions on the ground "epitaphs." The so-called "epitaphs" of many historical celebrities are actually the inscriptions on the tombstones of these people. For example, Shakespeare's tombstone is engraved with his last words: "For the sake of Jesus, my friend, don't touch the loess underneath." . Whoever lets me rest in peace may be blessed by God, and whoever removes my bones may be damned forever. "These tombstones are still intactly placed outside their tombs, and the famous quotes engraved on them were never "epitaphs."
