What does it mean to love burial?

It is said that in ancient times, some people dug up their clothes and buried them, calling them "cenotaph"; I also heard that some people in ancient times dug up bald pens and buried them, calling them "pen graves"; Dig a hole and bury your love letter, so it's called "love grave". The owner of the cenotaph, whose literary talent is romantic, has been passed down through the ages; The owner of the pen tomb, calligraphy claimed to be a family, and later generations rushed to spread it; The owner of the tomb of love has accomplished nothing, is trapped by love, longs for love and sympathizes with the world. People who bury their clothes are honored as writers; Bury the author, everyone respects him as a calligrapher; People who bury their feelings are called "lovers' infatuation"
