Does anyone know anything about cotton wool?

Cotton green is used to make green balls.

Green leaves are a kind of weeds, which grow in places with sufficient water and soil, and are most abundant on the ridges of fields and beside water paths. The oval tip and spoon-shaped palm are covered with a thin layer of fluff, like a blooming water lily. Gently pinch off the tender stems. Can pull up half an inch of wool.

Grandma said this kind is cotton green, which is the top grade of green. There is also a kind that looks like chrysanthemum leaves with smooth stems and leaves. Most of them grow on the roadside, and when they are made into green balls, they are far less fragrant than cotton.

Wrap the washed green leaves in gauze, soak them in water and boil them. After taking it out, it is only the size of a bowl, and it looks good. Put it on the chopping block, cut it into pieces, and then knead it into dough with refined white glutinous rice flour, which will soon become green dough.
