What do you mean, the three generations of Lao Na's ancestors were Taoist priests?

This is a sentence in a joke. Q: Are you a monk? The monk said: I dare not talk nonsense. My ancestors were all eminent monks for three generations.

Monks are not allowed to get married. How can there be three generations of ancestors? This is a satire and a whipping to the evil deeds of all beings in the last days, such as counterfeiting my clothes, peddling Buddha and creating various businesses, all of which are about not becoming a monk.
