In The Analects of Confucius, there are "teachers who are gentle, kind, respectful, thrifty and tolerant." Among them, "frugality" is frugality. Confucius has five virtues, including frugality, so he can win people's trust. Mozi also strongly advocated that clothing, food, housing, transportation, burial and other aspects should be "formulated into a frugal law" and "saved" in line with "heaven's virtue" Extravagance and waste means "depriving people of food and clothing and wealth" and infringing on others' right to exist. Zuo Zhuan said: "frugality is also a virtue, and extravagance is a great evil." Take thrift as the foundation of self-cultivation and extravagance as the root of all evil. Zhuge Liang said in the Commandment: "A gentleman's trip is to cultivate one's morality by being quiet, to cultivate one's morality by being frugal, to be indifferent to one's ambition and to do nothing." Over the years, in various periods of social development in China, hard work, simplicity and thrift, as a traditional virtue generally recognized by society, have been advocated, maintained and carried forward. This is also an important factor for China to grow from small to large and from weak to strong.
