In Kingsor’s Last Summer a character quotes this old Chinese poem
Life passes like lightning whose brightness there is hardly time to see
Although the earth and the sky stand still,
How swiftly time flies over the face of man.
Oh, you, who are before a full glass and do not drink!
Tell me, who are you still waiting for?
The book says it’s by Li Tai Pei and I think this is the same poet as Li Baihttps://en.m.wikipedia.org/wiki/Li_Bai
