Why do some people say that if they want to develop in calligraphy in the future, it is best not to learn from Liu Ti?

Many people in front of me are talking nonsense. As a calligraphy lover who has written Liu Zi for several years and is still "sustainable", I can tell you responsibly. There is nothing wrong with learning willow characters. The main thing is to have a good grasp of the degree. Learning Liu Zi can get the best gauge, which is an advantage. If you pass the degree, your writing may be stiff, which is a disadvantage. So we should grasp that degree. Don't write for too long, not more than three or four years at most. It is understandable to say that some people have criticisms of the word Liu. Even Yan Zhengqing's words have been said by some great calligraphers since ancient times that he is the ancestor of "ugliness, evil and strangeness" and that he is too vulgar. But the more modern, the more people say he is good. So never mind what some people say. You should have your own opinions. Write whoever you like. As long as it is a classic that has been proved by history, choose it at will.
