When you want to fall forward or to the side, you should actively bend your knees and squat, use your hands to support the ground to reduce the strength of the fall; when you want to fall backward, you should also actively bend your knees and squat to lower the center of gravity as much as possible. Let the hips sit down first, and pay attention to protecting the tailbone. At the same time, keep your head down to avoid falling back and knocking on the ground. When you fall, you should try to avoid straight arms on the ground with one hand, which can easily damage your wrists.
Skateboarding, try to choose a place with a wide view and a gentle slope when the weather is clear and visibility is high. Wear protective gear when playing to avoid chasing and playing.
