The topic is to ask Liu Hulan, who is young but ambitious. Does this remind us of a famous saying of Zhuge Liang? Quiet to cultivate one's morality, frugal to cultivate one's morality. Although Liu Hulan is young, he has great ambitions, which reminds us of Zhuge Liang's famous saying: Be quiet to cultivate one's morality, and be frugal to cultivate one's morality. Quiet to cultivate one's morality, frugality to cultivate one's morality comes from Zhuge Liang's book of commandments: a gentleman's journey is quiet to cultivate one's morality, frugality to cultivate one's morality, not indifferent to ambition, not quiet to be far away.
