Kangxi and Qianlong lived a long life because they paid attention to scientific health preservation and self-discipline. On the one hand, both Kangxi and Qianlong are good eaters, and he has always maintained very good habits in his life. Kangxi ate regularly every day, only two meals a day, and did not eat other useless things, especially alcohol and tobacco. Gan Long is very self-disciplined, and he can remain self-disciplined as always, which is why he has been in power for more than 60 years.
Another point is that Kangxi's mentality is particularly good. As we all know, once people are in a happy mood, they seldom get sick. Unlike other emperors, Kangxi and Qianlong were not afraid of death. They think it's human nature that people are born and die. They have accepted letting nature take its course, so they are in a good mood, and it is with a good mood that they have lived so long.
We should live like these two emperors, keep a happy mood and live a self-disciplined and orderly life, so that we can live a long life.
