Ceng Shiqiang was really startled when he heard this sentence.

At the age of 42, Professor Ceng Shiqiang met a kind fortune teller. The fortune teller told him, Professor Zeng, you should be careful, you won't live for three months. Ceng Shiqiang quickly asked the fortune teller how he knew. Mr. Wang showed him his tongue. When Ceng Shiqiang looked in the mirror, there was something wrong with his tongue.

Professor Zeng was surprised and asked the fortune teller what evidence he had. The fortune teller said, I've seen this before, and no one has lived for three months.

When you talked to me, I saw a square mark on your tongue. Professor Ceng Shiqiang knows that you can really see a lot from your tongue, so please tell him thank you, and I'll pay attention.

But Professor Ceng Shiqiang studied the Book of Changes deeply, so he knew that what the fortune teller said was wrong. But he is also curious about his tongue. Why is there such a mark? It suddenly occurred to me that a friend gave him some ginseng. These ginseng are all made into squares and contained in the mouth, and there is a square mark on the tongue. Later, Mr. Zeng said that in fact, the fortune teller was right, but he didn't understand the situation. If a person's tongue is born with square marks, he won't live long. I can live a long time.

Therefore, in the Book of Changes, six hexagrams are exchanged: introduction and exchange. Just don't say too much Don't tell him unless someone asks, and don't tell him unless someone asks you sincerely. And to what extent you want to tell it, you have to tell it, or you will be in trouble. This is the train of thought of the Book of Changes.

In The Book of Changes, Professor Ceng Shiqiang clearly and thoroughly explained the seemingly abstruse truth in plain language. The purpose of his doing this is to uncover the mystery of the Book of Changes, so as to provide reference for modern people.

This is a real book of avenues, including not only the laws of natural changes in heaven and earth, but also the principles of human society. It can be said that it is the best choice to improve your thinking and broaden your horizons.
