Sun Xiaoyun's calligraphy belongs to the category of calligraphy. He is an orthodox calligrapher with statutes and kung fu. I have seen a video of Sun Xiaoyun's writing, which seems to be "Postscript Mi Shu Fei Cycas". I think her kung fu is still very profound. As for calligraphers who occasionally make a few mistakes, it is normal to have typos and alterations in ancient times. Isn't the Preface to Lanting Collection marked with many alterations, deletions, additions and deletions? Mr. Tian once said in a calligraphy program that the word "dissatisfied and self-sufficient" in Preface to Lanting Collection cannot explain why the word "dissatisfied" means unhappy, but the context of Preface to Lanting Collection expresses a very happy situation. Therefore, the old man Tian thinks that the correct word here should be "quick self-sufficiency", and Wang Xizhi is proud and comfortable. Because of the influence of speed and emotion, it is entirely possible to make mistakes, and future generations will make mistakes, so it will be handed down.
When you look at a work or appreciate a calligrapher, you don't need to be picky, you need to look at the overall situation. Calligraphy with profound brushwork is good calligraphy.
Calligraphy theory written in the book On Twisted Tubes, which was criticized by Mr. Tian. Personally, I don't think "twisting the drum", but I still think Sun Xiaoyun's calligraphy is very good. I didn't see Sun Xiaoyun's "Twisted Tube" when she wrote the video "Postscript Cycas". In ancient calligraphy theory's works, it seems that few people regard "twisting cylinder" as a kind of brushwork. In order to achieve a certain effect, it is acceptable to twist the pipe occasionally. If it is too much, it obviously violates the way of calligraphy with a pen, and this theory is not worth taking.
Sun Xiaoyun was born in 1955. He was very young when he wrote that video, but it can be seen that he has deep skill. Recently, Sun Xiaoyun was honored as the chairman of the Book Association, and someone on the Internet exposed Sun Xiaoyun's discarded brush, which is said to have more than 200 tubes. Even if there are exaggerated elements, it is quite hard work. The ancients said that "the pen is buried", and the practice of calligraphy should be like this. I believe there are many people who work so hard.
The chairman of the book association has changed, and it is time to rectify the chaos of calligraphy.
