On the problem of ancient Chinese calligraphy

hello, I'm brother jade. The ancients used a brush to write, so calligraphy and a brush were inseparable from life for the ancients. We can imagine that the teacher assigned more homework, and you, too, stopped writing, and then the handwriting began to fly wildly. When attending an important occasion, or someone comes to beg for words, I am very happy, and then I start the beep mode. Therefore, a person's mood is related to his works. When learning a person's things, we should combine the time of his works. Politics, economy and culture together judge his intention of writing.
