1. First, let small fish plate slide, as shown in the following figure:

2. Then step on the skateboard with the center of gravity, and put the other foot on the ground for friction, as shown in the following figure:

3. Then, with the increasing friction, the small fish plate will gradually stop, as shown in the following figure:

4. When small fish plate is in a sliding state, as shown in the following figure:

5. Use small fish plate's tail to step down hard, and generate friction with the ground, as shown in the following figure:

6. Through the friction between the tailgate and the floor, the braking effect can be achieved, as shown in the following figure:
