Kangxi's attitude to the so-called "immortality" was correct. He believed that human life, from birth to death, is a natural process that cannot be stopped. Therefore, people can only conform to nature and take more maintenance in order to prolong life within a certain range.

Kangxi believed that the key to good health is to eat properly, not to be partial to it, let alone overeating. You should pay attention to your own situation and eat reasonably. As Emperor Kangxi, his courtiers naturally did their best to flatter him and invite him to pet him. He loved to eat fruit, so officials from all over the world rushed to pick fresh fruit for tribute, but he never ate much, always tasting a little was enough. "These fresh fruits are not ripe enough," he said. Eat them when they are ripe and smell sweet; otherwise, it will not benefit your health."

Every time Kangxi went on tour, he always rejected those banquets that were delicious from the mountains and seas, and ate only seasonal dishes produced locally. "The elderly should eat some food with a lighter taste and eat more vegetables, so that they will get less sick," he said. For those who were unsympathetic, tried their best to scavenge the people's fat and folk ointment, rectify the rich banquets to please themselves, and strive for promotion, Kangxi was unceremoniously dismissed and immediately investigated.

Kangxi's requirements for drinking water were very high. Generally, the water should be heated and boiled, and distilled water should be used for drinking. Whenever it rains heavily or floods break out in summer, he never drinks river water. He believes that the river water at this time is easy to get sick after drinking, because floods can easily initialize harmful minerals, feces and even rotting animal carcasses on the surface and mix them with the river water, which is of course very unhygienic.

Because of this, Emperor Kangxi ascended the throne at the age of 7 and was emperor for 61 years, second to none in our country or even in the world. During his reign, he successively quelled the rebellions of Wu Sangui, Geng Jingzhong, and Shang Zhixin, recaptured Taiwan, and fought against Tsarist Russia. His life can be described as busy and busy, with a lot of opportunities. But under such circumstances, he was still quick-thinking and strong until his later years.
