1, don't put your hands in your pockets when you walk, or you will easily get hurt when you fall.

Be extra careful when going up and down stairs or steps. It is best to hold handrails or other fixtures.

3. Don't chase and fight on the slippery and icy road, otherwise it will easily cause injury accidents.

4. When walking on ice and snow, it is best to wear non-slip rubber shoes, try not to wear flat shoes without patterns, keep your body center of gravity low, and always pay attention to driving conditions.

When crossing the road, you should stand on the side of the road and adjust the angle of your hat and umbrella to avoid blocking your sight. Only when there are no vehicles coming around can you pass carefully.
