班主任容嬷嬷是你娘吗
[bān zhŭ rèn róng mā mā shì nĭ niáng ma]
This name 'Class Teacher Mother Rong is your mother?' uses a pop culture reference from a Chinese palace drama where Mother Rong is an authority figure. The name playfully questions the relationship between teachers (authority) and students in an informal, almost defiant manner.
