Wang Xizhi wrote and typed a two-part allegorical saying.

Hit the nail on the head. This idiom is mainly used to describe the strength of calligraphy, and now it is often used to describe a profound and thorough understanding of articles and things. This idiom originated from Wang Xizhi at the end of Shu: "When the Jin emperor offered sacrifices to the northern suburbs, he wished more editions, cut them by workers and wrote incisively."

Many people may wonder what kind of power can be used to carve three points on wood. In fact, this is a wrong understanding. Carving three points on wood is not done with a pen, but the ink of the written words permeates into the wood. In ancient times, people had to write on wood with ink instead of plaques, so that the corresponding characters could be carved with knives. In this story, Wang Xizhi's handwriting is vigorous and powerful, and it took a carpenter three-inch wood carving to carve all the ink, which shows Wang Xizhi's calligraphy.

Precautions:

Wang Xizhi is a famous calligrapher in China. His Preface to the Collection of Lanting was copied by calligraphers in past dynasties and was called "the best running script in the world". There are many stories about his calligraphy practice, except "getting to the point".

According to legend, when Wang Xizhi was a child, he would go to the pond outside the house to wash his pen and ink stone every day after writing. After a long time, even the water in the pond turned black. According to legend, Wang Xizhi saw a poor old man selling fans on the roadside and wrote some words on the fan to let the old man sell them in the street. The old man was puzzled at first, but all the old people sold it. It can be seen that Wang Xizhi's calligraphy is highly respected not only now, but also at that time.
