How to draw a clear mind map

Qingming's mind-guided painting method is as follows:

First, draw a picture of a shepherd boy riding a ox, with Tomb-Sweeping Day written on it and a red branch in the upper right corner, mainly introducing Tomb-Sweeping Day's introduction. Introduce the name, time and significance of Tomb-Sweeping Day. Draw a green branch in the lower right corner to introduce the origin of Tomb-Sweeping Day. Tomb-Sweeping Day is an official festival in the Tang Dynasty, which replaced the Cold Food Festival in the Song and Yuan Dynasties. Draw a brown branch in the middle of the left to introduce the local food in Tomb-Sweeping Day, Amigo and Qingtuanzi. Draw a rose branch in the lower left corner to introduce the customs of Tomb-Sweeping Day, mainly grave-sweeping activities, ancient Tomb-Sweeping Day and modern Tomb-Sweeping Day.

Tomb-Sweeping Day, also known as outing festival, outing festival, March festival, ancestor worship festival, etc. It was celebrated at the turn of mid-spring and late spring. Tomb-Sweeping Day, which originated from the ancestor belief of early human beings, is the biggest ancestor worship festival of the Chinese nation. Tomb-Sweeping Day has two connotations: nature and humanity. It is both a natural solar term and a traditional festival. Grave-sweeping and outing are two major themes in Tomb-Sweeping Day.
