Drunk in the mountains, feeling light and wanting to go to heaven. How to write a good cursive script?

Drunk in the mountains, feeling light and wanting to go to heaven. Cursive writing looks good according to the structure. Calligraphers in past dynasties paid special attention to the primary and secondary contrast of lines, and often used the strokes that best expressed the calligrapher's personality as the main pen to show their unique aesthetic feeling. For example, Yan Zhenqing is full of needles, the Yellow Valley is full of twists and turns, and the vertical hooks in Mi Fei are unique. In addition, there are many contrast techniques, such as size, vertical and horizontal, back to back, tilt, density, thickness, shadow and Fiona Fang.
