老师是容嬷嬷的女儿
[lăo shī shì róng mā mā de nǚ ér]
In this context, 'the teacher is Rong momo's daughter' is likely an indirect reference to a strict but kind teacher in Chinese culture. In Chinese media, Rong momo is often portrayed as a meticulous and traditional old woman, implying her daughter might be quite disciplined too. This reflects respect for the teacher’s stern but nurturing qualities.
