1. Write the word "jiaozi" on the paper with a pen, so that the font size and line thickness are uniform and the strokes should be smooth.

2. On the periphery of the word "Jiaozi", draw a slender hollow rectangle on the edge of the font with the same pen. The width of the rectangle should be matched with the font thickness to avoid disharmony.

Draw another line on the bottom and right side of the rectangle, thus dividing the rectangle into four small rectangles.

4. Trace the hollow part with a fine pen to make the font clearer, and you can draw beautiful intersecting hollow characters.
