What does it mean to send a bronze mirror to the sea when the moon rises?

The bronze mirror can be well dressed, which shows that Luo Jitong's conduct is improper and his virtue is detrimental.

Yining gave Luo Ji the same bronze mirror, which means that she should take a good look in the mirror. Don't be wishful thinking Some of her little moves can be seen in her eyes, which is also a kind of rejection, because she doesn't want Cheng Shaoshang to misunderstand. Luo Ji pestered Cheng Shaoshang again and told Cheng Shaoshang that Yining was very good to her.
