What techniques are commonly used in cloud in Chinese painting?

It can be dry dyed or wet dyed. First, draw a rough outline with a carbon ribbon. When dry dyeing, dip the pen in unsaturated water, dip the nib in ink, and quickly drag the nib down according to the outline drawn by the carbon tape. When wet dyeing, first draw a rough outline with carbon strips, then spray water on the rice paper, and then dip the pen tip with less water in ink. The method is as above. If there are few clouds, use a big pen; if there are many clouds, use a small pen.
