1. Prepare a piece of paper and two colored pens.

2. First, use a brown pen to draw two oval shapes nested together on the paper to represent the pattern in the middle of the mooncake.

3. Outside the two ovals, draw another ellipse composed of arcs to represent the outline of the mooncake surface.

4. At both ends of each arc, draw a line leading to the middle oval to represent the pattern.

5. From both ends of each arc, draw a vertical line downward to represent the pattern on the side of the mooncake.

6. Connect each vertical line with an arc to represent the bottom of the mooncake.

7. Finally, use orange to paint all the mooncakes orange, and the mooncakes are finished.
