As for why they are so called, it is because there is a word in their names that is the same.

The name of Yao Zheng's fans is because Yao Zheng sang "Wait until the oil cake is finished" (it seems to be this name) ... The names given to fans are all decided after the fans think it over and the idol himself agrees.
