"If a general fails to give an order, the army will be destroyed" comes from Lv Shi Chun Qiu·Sishun Lun

Translation:

If a general gives a wrong order, he will be killed. Resulting in defeat and death. If a monarch says the wrong thing, the country will suffer disgrace and will be ridiculed by future generations. It shows that those in power must be cautious in their words and deeds. A little carelessness may lead to catastrophe.

"Although Chu has three households, Chu will definitely destroy Qin". This famous saying originated from the era of resistance to the violent Qin rule. It comes from "Historical Records of Xiang Yu" written by Sima Qian in the Western Han Dynasty. It means that even if there are only a few families, the Qin State can be destroyed. Although the metaphor is small, success can still be achieved with great determination. It represents an emotionally charged belief.
