毛爷爷脸红的时候最值钱
[máo yé yé liăn hóng de shí hòu zuì zhí qián]
This playful name refers to Mao Zedong with great respect using 'Grandpa Mao'. Adding that 'When he blushes he is most valuable' could evoke a lighthearted and endearing portrayal of this historical figure in moments where humility or unexpected emotions like embarrassment occur, blending history and sentiment into a personal touch.
