Material preparation: paper and brush.

Painting steps:

1. First, prepare a wide piece of white paper, and spread it around from the center of Japanese paper by divergent thinking and association.

2. Construct the core center of mind mapping. Write a keyword or theme in the center of the white paper and circle it with colored pens.

3. The use of colored pens is also very particular. For example, the 24-color pen can make the mind map light up, but it is not used casually. Make sure that the color of the brush is related to the keywords related to divergence.

4. Mind mapping is like a big tree, which can be simplified into one, two and three branches. Branches of different levels are connected by soft curves.

5. Both ends of branches are keywords of mind map, and branches of different levels can be distinguished by font size to make the visual effect more beautiful.
