The supreme ruler still has something that restricts him. After Emperor Wu of the Han Dynasty respected Confucianism alone, Confucian classics became the moral basis and legislative basis of the rulers. Mencius said that the people are the most important, the country is the second, and the monarch is the second. According to this standard, if the emperor is morally strict with himself, he must do it according to this. Of course, people-oriented is just a slogan of the rulers, which is equivalent to "serving the people" in contemporary times. Slogans should be shouted not only, but also loudly, so the worst thing is corrupt officials, not emperors.

Another criterion of moral restraint is filial piety. Rulers always say that "the world belongs to Mao". Except for a few emperors who want to become immortals, most emperors are more realistic. They know that sooner or later, they will become portraits and memorial tablets of Fengxian Hall, and the throne they created or took over will eventually be passed on to their descendants. An emperor who has high standards for himself will want to govern the world well before he can be worthy of his ancestors. Second, they will still be themselves.

The third is to consider your own historical position. The ancients in China were very concerned about what was behind their own names, which led to Premier Wen's "keeping the heart of Dan as a mirror of history" and "Confucius said benevolent, Mencius said righteous, so benevolent". The emperors enjoyed all their wealth before their death. Since history has proved more than once that immortality is unreliable, what is there to pursue? It is a memorial and glory after death, and it is an eternal glory.

However, these constraints require the emperor's self-discipline, but why can only the Qing Dynasty ensure that every emperor is diligent, and all previous dynasties can't? That's because the Qing dynasty paid special attention to the education of the prince. From birth, the prince had to leave his mother to be fed by a wet nurse so as not to be spoiled by his mother. In addition, from the age of five or six, the prince will study in the study before dawn, and also practice storing cloth, riding and shooting. He has formed the habit of working hard since he was a child. Under such strict to almost harsh requirements, as long as the princes can grow up, they can ensure strong physique and vigorous energy, and those who fail will be eliminated. Third, the Qing Dynasty established the national treasury in order to establish wise men, not long men, except that there was only one son or no son at all in the later period.

You said Kangxi Qianlong was tired of politics in his later years. On the one hand, I feel weak when I am old, on the other hand, I feel that I have achieved the above, and my spirit is empty and I have not pursued it. Of course, Kangxi was also hit by the spirit of various scholars contending. . . This is somewhat similar to that of Xuanzong of Tang Dynasty, who initiated the prosperity of Kaiyuan in history, except that the two emperors of Qing Dynasty did not have Yang Guifei or An Lushan, and did not make the mistake of Xuanzong of Tang Dynasty.

The emperor has never been immune to beautiful women. Most emperors died in their thirties. Where did more than 30 sons of Kangxi come from, not including the princess, let alone Qianlong. People in their eighties are still recruiting women to the palace.
