Ask humbly (Chinese painting) how to draw a landscape painting "Waterfalls and Running Water"? And how should Song Xiu write?

Waterfalls are called springs in Chinese painting theory, which are caused by geological faults or tendencies, especially in volcanic rocks and granite terrain. Its types can be divided into rock overlapping springs, cliff hanging springs, mountain branch springs, waterfalls and so on. The role of waterfalls runs through the whole landscape like blood, so we should first pay attention to its source. Without hanging the top of the mountain, draw the dynamic potential and underwater sound of the flying jet at the same time. Shuikou is the most difficult to draw, so be creative. The ancients painted waterfalls with smooth lines to express the fluency and speed of water flow, and blackened the rocks next to them to set off the beauty of white practice. In recent years, the great waterfalls painted by Shen Quan in Qing Dynasty or Huang Junbi now have their own characteristics, and the rolling spray is solidified with bucket lines or short lines. Pine trees symbolize human gentlemanly demeanor and longevity. The ancients loved to draw pine trees, showing the spirit of being tall and straight, vigorous and indomitable. Pine bark has scales. Painting pine bark should be vigorous and hairy, and the arrangement should not be too regular. Pine leaves are needle-shaped, and there are many different painting methods, such as semicircle, circle, ponytail and zigzag. Pine leaves are dry and straight, and bend when they are born in crevices.
