班主任是容嬷嬷的孩子
[bān zhŭ rèn shì róng mā mā de hái zi]
Here 'the head teacher (usually refers to the main educator in a classroom) is the child of Empress Rong from Story of Hong Lou Meng, who is a traditional strict and authoritative figure. So in modern context, this netname suggests a humorous complaint toward the severe disciplinary measures used in education. It hints at an unorthodox way to comment on school regulations or authority using familiar figures from popular historical dramas.'
