Restraint and temperance are rational control of personal desires. Desire is like sea water. The more you drink, the more thirsty you are. Therefore, the so-called moderation in treating people is actually to restrain one's own desires, not to indulge, and not to do whatever one wants.
People in high positions tend to get carried away and use words instead of laws. Most people who get rich overnight and are worth millions spend a lot of money to open the way. In fact, these behaviors are indulgence and self-destruction. A simple truth: people's desire for food and sex can be described as a fundamental desire. If you indulge yourself without restraint, overeating, overeating without restraint; If you have sex every day and have orgasms every day, I believe that it won't be long before you say goodbye to your health.
Sima Guang said that it is very difficult to go from frugality to extravagance and from extravagance to frugality. He treated people with such a thrifty attitude, and borrowed ancient metaphors to write a History as a Mirror. In the American novel The Shogun, General Yin Yong, based on Tokugawa Ieyasu, is a model of extreme moderation: every time he spends money, he always draws up a quota in his mind, but when he tells his servants to carry it out, he always cuts it by half-only in this way can he finally win the Shogun War, and so it is.
