What does the flesh and blood in Zeng Guofan's letters mean?

The flesh and blood in the first sentence is not about your children, but about your pride, which is very arrogant.

The second sentence is that you should go to school early to learn knowledge and be a man, and receive cultural education early.

The third sentence says that when you are about 36 years old, there will be a turning point in your life.

The fourth sentence is about taking off blue clothes, that is, taking off students' clothes, which shows that they have some experience. In ancient times, changing the red robe was an official. In modern times, it refers to a smooth career, that is, the road to life in the future is smooth sailing.

Many modern people also like to listen to some fortune-telling words. In fact, these words have no factual basis. Many are ambiguous, and everyone's understanding is different. Finally, it is impossible to determine whether the calculation is right or wrong. So the impression is that the calculation is very accurate. This is actually a speaking skill.

Just laugh off these criticisms, don't be too obsessed with what you say, keep a normal heart, be kind to others, do good deeds, and don't have too much desire for life, and you will naturally see all kinds of income in life.
