This idiom was originally used to describe Wang Xizhi's exquisite calligraphy.

This idiom originally described Wang Xizhi's calligraphy as very vigorous and powerful. Wang Xizhi once wrote an inscription on the wood for the Eastern Jin Emperor during the sacrifice. But later, when the carpenter was carving wood, he found that the ink written by Wang Xizhi had penetrated into the wood, which was three points away from the surface of the wood. Therefore, the Eastern Jin Emperor thought that Wang Xizhi was a rare calligrapher in history. In fact, Wang Xizhi's calligraphy is unparalleled so far.

First, the incisive three points reflect what realm Wang Xizhi's calligraphy has reached. This idiom reflects that Wang Xizhi's calligraphy has reached a superb level. Now people evaluate a person's calligraphy, first of all, to see whether the words are vigorous and powerful. Because most of the ancient Chinese characters in China are pictographs, many literary experts believe that every Chinese character in China comes from a beautiful picture. If you want to write Chinese characters beautifully, you must first be serious, and then you must put pen to paper when you write.

However, Wang Xizhi encountered many setbacks when practicing calligraphy. In fact, Wang Xizhi's handwriting was not particularly beautiful at first, and he even suffered ridicule from his father. But Wang Xizhi was not discouraged by this. In order to improve his calligraphy level, Wang Xizhi began to write day and night. In ancient times, because there was no running water, Wang Xizhi went to the pond in front of his house every time he cleaned the pen and inkstone. After a while, Wang Xizhi's father was surprised to find that the water in the pond in front of his house was dyed black by ink. It can be seen that Wang Xizhi practiced calligraphy very hard, and it is precisely because of this that Wang Xizhi's calligraphy can reach the incisive realm.

Second, what is the significance of penetrating three points in today's society? In today's society, penetrating three points does not mean boasting how high a person's calligraphy level is. Agility mainly refers to whether a person's ability to understand the whole thing is thorough. Therefore, when many students do Chinese reading comprehension, if the analysis of the problem is very thorough and the understanding ability of the whole thing is very transparent, then the teacher usually praises the student's incisive analysis of the problem.
