[Lukongsimi]

The proverb "Never cast your pearls to the pigs" means not to waste valuable things or good advice on those who won't appreciate or understand them. It's about recognizing when efforts to help or share something meaningful are being wasted because the recipient is unwilling or unable to value what's being offered. The phrase originates from a biblical passage in Matthew 7:6, where Jesus uses the imagery of pigs trampling on pearls to illustrate this idea.
