容嬷嬷没有底
[róng mā mā méi yŏu dĭ]
Referring to Rongmom, who is a character (grand nanny) in an ancient Chinese TV series named 'Empresses in the Palace'. This name, translating as 'Rongmama has no bottom', uses humor or satire to make a play on words implying endlessness or depthlessness, perhaps hinting at having many unknowns or stories to share.
