Calligraphy is forbidden without losing its agility. Regular script is solemn and solemn, and it is strictly forbidden to be steady. If it is regular script, Mo Yu will let the whole work be scrapped. Running script is light and lively. As long as it is not too outrageous, the remaining ink has little effect on the work. The most famous is Preface to Lanting Collection, which uses ink casually and skillfully. As for the cursive script, it is rigorous and neutral, and the scale is wild and chic. The most important thing is to be free and easy, and even to be a stroke of genius.
Calligraphy is a rigorous art, with three years of regular script and five years of running script, and it has just started in ten years. Go wild if you want, and do whatever you want. I haven't had a book for twenty years.
