"Nothing is sadder than silence": Personally, it comes from "a thousand troops can grieve", which was extended and put into use. The saddest thing is that all the subjects in the government and the people of the country are silent.
Gong Zizhen's "Qian Hai Za Shi"
Kyushu is furious.
It is sad to study it;
I suggest that god stand up again,
Don't stick to a model and leave behind talents.
The two sentences express the accusation of "giving up" and "silence" in the society. They think that if the society and the country want to make progress, everyone must have ideals and expectations in their hearts, and everyone can speak freely and not get married. Only in this way can we promote the emergence of new ideas and technologies and further liberate the productive forces.
