How is teacher Fang's calligraphy? Is there much room for appreciation?

I have met several teachers in Guangdong, and I am amazed by their basic skills and seriousness. I invited a few words, all of which were very rigorous. Not only did I fold Mi Zige in big letters, but I also had to think for a long time and check the posts. But when I wrote it, I felt smooth and solid, and I felt that I had better brushwork and ability than those so-called contemporary celebrities. Maybe he doesn't like the pursuit of fame and fortune. I only spent 1 500 on three words.
