1. Put the paper horizontally. The biggest theme (the title or title of the article) should be reflected in the center of the whole paper in the form of graphics, which is called the central map. The picture in the middle should have more than three colors. The layering should be clear, the line closest to the middle should be the thickest, the line extending outward should be thin, the font near the center figure is the largest, and it gets smaller later.

2, a theme and a big branch. Mind mapping embodies the theme in the form of big branches, and there are as many themes as there are big branches. Each branch uses a different color, so that you can see the relevant information of different topics at a glance. For example, take Robinson's three adventures as the main branch, the third adventure as the main content, and time as the clue to draw what happens every year in the small branch.
