What does it mean to re-polish the old mirror?

"The old mirror is reground, and the bright moon is round": it means that the fate at this time is as bright as the old bronze mirror after regrinding, like a bright full moon. The so-called "old mirror", that is, "the initial limit of 23-24-27-89", once had good luck, and this is the second good luck arrival.

If it is used to describe people, it can be explained as follows:

"The old mirror is re-ground, and the moon is round." It means that couples or lovers come together again after breaking up, just like a polished iron mirror, as bright as ever, and the bright moon after the crescent moon becomes a full moon.
