How to practice Tian Yingzhang's calligraphy (the key point is that my handwriting is untidy and looks irregular)

Take the vertical hook as an example: draw the pen vertically in the center, and when it reaches the lower end, use the lifting button to initially form the shape of the hook to draw the head (this is very important! The specific writing method is as follows: when reaching the lower end, press it first and then lift it, so that the raised front point almost touches the paper, and then press it to the left (at this time, the front point is behind and the pen belly is in front, just like the front point of the pen tip is the foot, the pen belly is the knee, and the pen tip "kneels down"), and then "bounce" the front while lifting the pen.

This is my experience of watching Tian Yingzhang's videos and practicing many times. The above description is a little simpler than what Tian actually wrote. My writing method is to press to the left after lifting the pen, kneel down and bounce the front; Most of Tian Yingzhang's teachers raise the nib, and then it goes down along the lower right edge of the vertical painting. After adjusting the shape of the hook, they kneel down and play the pen. Tian teacher was even "frustrated", and then he knelt down and wrote.

It should be more detailed and clear. You can watch more videos of Tian, experience more, practice more and think more. I believe that many good things will be rewarded.
