Don't sing "yellow chicken with white hair", use Bai Juyi's poem instead, which means don't sigh that time flies. Bai Juyi said in the poem "Drunk songs show prostitutes are exquisite" that "yellow chickens urge the morning" and "daytime urges the years". People are getting old day by day in the course of yellow chickens crowing and daytime running, so he lamented that "HongLing's waist is unstable, and Zhu Yan is blind in the mirror". Su Shi did the opposite here: "White hair doesn't sing yellow chicken". "White hair" refers to old age, and "yellow chicken" refers to the feeling of years flying in Bai Juyi's poems. Don't be pessimistic because you are old, life will be youthful.
