Students in Xinjiang have classes in foggy and snowy days like explorers. What should they pay attention to in this weather?

Keep warm and stay away from trees, etc. In this snowy weather, the temperature will be very low, so students need to wear more clothes to avoid catching a cold and other symptoms. This level of heavy snow is often very thick, which will cause many trees to collapse easily. Be careful to stay away from these trees to avoid being hit by them.
