What is the meaning of calligraphy? thank you

Hello, calligraphy is one of the techniques of Chinese painting. Chop means chop. The pen tip cuts obliquely from the air to the paper surface quickly, and still runs for a period of time after touching the paper, forming the effect of virtual pen and real pen, such as chopping the board with a knife and axe, but in the opposite direction to the chopping method with an axe. This painting method is often used to draw lines on slopes and trees. If you want to practice calligraphy well, it is recommended to use calligraphy tools such as calligraphy three treasures, which has made rapid progress and I hope to adopt them.
