"The prosperity of the people is suffering, the destruction of the people is suffering" is not a flat lament, but a spiral:
——To die is to burn human life as firewood;
——Xing means pressing ashes into bricks to build a new city wall.
In Zhao Sanhu's sixteenth year, he just changed from "burned" to "built up", and then to the ashes "sitting at the base of the city wall drinking".
The last sentence he cursed, "What a rude and rude person", was actually the most polite and rude greeting for all "people who have been passed by by history".
