当年容嬷嬷是京城1枝花
[dāng nián róng mā mā shì jīng chéng 1 zhī huā]
'Nanny Rong from Dyansty Drama was once the top beauty in Beijing.' This name humorously refers to someone who was once famous or admired for their looks or abilities, using the pop culture reference of Nanny Rong from 'The Story of Empress Dowager Cixi.'
