给不了她嫁衣就别脱她内衣
[jĭ bù le tā jià yī jiù bié tuō tā nèi yī]
This name, translated directly, is quite suggestive: 'If You Can’t Give Her A Wedding Dress, Then Don’t Take Off Her Underwear'. This signifies respect towards others and the seriousness of relationships. More colloquially it's warning against frivolous relationships that lack commitment.
