What does it mean to eat pigs with fur without butcher Zheng?

Butcher Zheng generally refers to killing pigs, as well as butcher Zhang and butcher Wang.

The original meaning is "when the butcher Zheng dies, he has to eat the pig with skin", that is, when the pig killer dies, no one takes his place, and no one loses pig hair, he has to eat the pork with skin. There are all sayings of "United pigs" and "mixed pigs", which have the same meaning. Describe the lack of an important link and the inability to do things normally.

But most of them are ironic, that is, "if there is no butcher Zheng, you won't eat hairy pigs." "If butcher Zheng dies, you have to eat hairy pigs?" , or "dead butcher Zheng, also don't eat pigs with hair". Fingering is not necessarily that important.
