Why was the note written by Wang Xizhi kept as a secret treasure by the Japanese royal family 1300 years ago?

This note is a funeral post about Japan, mainly because the Japanese royal family thinks it is an original, and because the original of Wang Xizhi is basically untraceable, the Japanese are greatly influenced by the Tang Dynasty, so they worship Wang Xizhi very much. At that time, because it was collected from abroad, it was not at home, and I was afraid of losing it again, so I could only keep it secret.

It is said that this "funeral post" in Japan is only a copy of the original by future generations. Because it will be the Tang dynasty when it is handed down, Wang Xizhi is very unknown in the Tang dynasty, so no one cares. This funeral post says that Wang Xizhi's ancestral grave was destroyed. Wang Xizhi is over fifty, but he is unable to maintain his ancestral business. He was very sad and wrote a hearty masterpiece with a sad mood. This post is blunt with a pen, with a long structure and various symptoms, completely getting rid of the remnants of Lishu and Cao Zhang. Because it was written in the spirit of his own inner sadness, later generations also called him a note.

However, many netizens think that what China people want but can't get is the best, so they think their books are particularly important. But because China is so powerful now, it is necessary to prevent China people from making plans (or being afraid of being beaten by China), so they don't even let people see it. But looking at this funeral post, it was a gloomy running script at first, but with the change of Wang Xizhi's feelings, it gradually became a cursive script that was about to escape. The strokes turn more and more smoothly and flexibly, with different shades of color, and the strokes are faster at the end of the paper.

In fact, there are very few calligraphy that can be handed down in ancient times, so many will become treasures as long as they stay.
