Fish sir Parent Circle is a parent support circle initiated by a big V named Fish sir. Teacher Yu himself graduated from Zhejiang University and has been serving parents in the education industry since graduation. Later, he turned the parent support circle into a self-media account and became the "Mr. Fish's parent circle". He often published the evaluation contents of children's English, mathematics, programming, Chinese and other courses, as well as educational guidance for parents. Therefore, it is not only a circle for parents to communicate, but also a self-media number.
