When watching the calligraphy exhibition, how can you talk about calligraphy as an expert?

The so-called people mind their own business. Look at the calligraphy exhibition, you can think about it, who would go without this hobby! So, either don't go, don't talk when you go, don't understand and don't talk, no one will treat you like a fool. Look at the calligraphy exhibition, at least you have this hobby, and you'd better know something about it yourself, such as seal, official script and cursive script. Liu, Yan and Ou have a basic understanding. To say calligraphy, we must know the words of praise, such as vigorous and powerful, meaningful, free and easy, beautiful and powerful, and everyone's demeanor.
