Material preparation: drawing paper and brush.

1. Draw a square with a pencil first. Then draw a circle on the four sides. Determine any point in the middle and upper part of the circle, and then draw a circle with this point as the center.

2. Fill the whole circle several times, 5 times and 6 times, which is the weft. Then make some earth meridians pass through the center of the circle evenly. Make some irregular land figures, which can be roughly expressed.

3. Black all the useful lines with a black ink pen. When the notes are dry, erase the pencil line. Because the earth is divided into continents and oceans, the land is painted green. Finally, the ocean can be painted blue to complete the drawing of the earth.
