1. Although Zhuge Liang is the prime minister of Shu and the commander-in-chief of the three armed forces, he is a model of integrity. He educated his son to cultivate noble character, that is, to cultivate morality through frugal life, to establish lofty ideals through indifference to wealth, to increase his talents through meditation, and to get rid of pleasure and laziness through uplifting his spirit. On his deathbed, Zhuge Liang not only made suggestions for his ancestors, but also stated his family affairs in a targeted manner, declining the reward in advance, so that future generations would not be great because of money.

2. Yue Fei was an honest and clean general in ancient China, who was a teacher. A prominent feature of his strict management of the army is that he is strict with himself. Yue Fei put forward two famous slogans: "Civil servants don't love money, military officers don't hesitate to die, and the world is at peace."

3. Tao Kan, a famous minister in Jin Dynasty, was a collector in Xunyang County when he was young. Once, he sent someone to send a can of fish with Chinese sauerkraut to his mother.

Tao Kan was deeply educated in this matter.
