What do you mean by pork buns?

Hello, the word should be: lard is blindfolded. It is also called lard to say that a person has no sensitivity and feelings for things outside. If lard is blinded, this person must have no pity, no tenderness, and no pain from relatives and friends. It's just right to call this man a pig's heart. Meaning: Don't begin to understand, or you will lose your conscience.
