When you are young, your blood is not mature, so you should restrain your lust. Young people's kidney qi and bone marrow are not full, which is a critical period for physical growth and intellectual growth. If you don't indulge in lust, it's like cutting down the tree of life, or hurting your body, or ruining your virtue, delaying a good time and making you accomplish nothing in your life. Color refers not only to pornography, but also to all human temptations.

After the age of 30, it is easy to fight with others for love, reputation, interests, face, women (or men). This kind of fighting is mostly emotional, not rational, and should be avoided as much as possible. If you are brave enough to fight, you will die of anger and even use a knife and gun to endanger society.

At this stage, it is more important for people to keep a normal heart and treat gains and losses correctly. Because the glorious stage of a person's life has passed slowly, people can't always live in the glory of the past. They should treat the gains and losses of interests indifferently, live happily and support themselves.

"The Analects of Confucius" says: "A gentleman does not have enough to eat and is restless." Food and clothing costs don't need luxury, just maintaining a normal life. Confucius lost his father at the age of three, his mother at the age of seventeen and a disabled brother to take care of. Although life is bitter, teenagers are inspired by reading, and they are also happy when they are poor: "Eating food and drinking water, bending their arms and resting on them, are also happy." Being rich through injustice is more expensive than me, like floating clouds. "

People's desires are endless, and teenagers' abstinence from sex is actually a temperate attitude towards life. Because of temperance, it is indifferent; Because of simplicity, I am happy. Therefore, we can finally understand Confucius' praise of Yan Hui: "One scoop of food and one scoop of drink, in the mean lane, people will be worried if they can't bear it, and they will not change their fun when they go back." A humble hut, a bowl of food and a ladle of water. ...

In the eyes of others, such a life is bleak and has no merit. However, this is all about Yan Hui. The days of the ascetic monk not only didn't make him feel sad, but faced it with a positive and sunny attitude and lived more happily and freely. If you covet enjoyment, your desire will be strengthened and your mind will be lost.

Putting aside vanity and wealth, being pure in heart can naturally strengthen the ideal. So we can see that Confucius later learned a lot and founded Confucianism; Yan Hui also became the head of Confucius' seventy-two sages and one of the five sages of Confucianism.
