It can be said that people in their fifties are as happy as the East China Sea and live longer than the South Mountain.

Traditionally, it is inappropriate for people in their fifties to say that they are as happy as the East China Sea and live longer than Nanshan. Although people nowadays don't care much about these traditions, just wish good luck. But it is said that people in their fifties are as happy as the East China Sea and live longer than the South Mountain. This is a satire and a curse to his short life. Because traditionally, happiness is like the East China Sea and longevity is like the South Mountain, all of which are for people over 60 years old.
