1. Draw a warning area in front of the box, and draw it with a yellow and black zebra crossing with a width of100 mm. The yellow and black stripes should correspond and cannot be staggered.
2. Brush yellow and black zebra crossing along the edge of the box. Brush the yellow paint first, and glue it with tape at a surface interval of 50mm, then brush the black paint.
3. The distance between the box in the warning area and the zebra crossing can be appropriately adjusted according to the actual situation.
