我最喜欢毛爷爷脸红的时候
[wŏ zuì xĭ huān máo yé yé liăn hóng de shí hòu]
Mao Zedong blushing—while 'Grandpa Mao' (referring respectfully to Mao Zedong) typically wouldn’t be personified this way—it likely plays on historical reverence with whimsy or nostalgia. It could be endearing if seen in personal terms rather than historically.
