Add a few restraining orders to rural primary school students. For example: don't go into the river, don't bathe in the pit; Stay away from transformers in villages or fields, and don't climb; Don't run around in the fields, lest you fall into the well; Don't climb the telephone pole; Don't take a bottle to drink water at home, because it may be a pesticide bottle; Don't play with matches and lighters, especially don't strike matches and lighters beside the firewood pile to avoid fire; Try to stay on the side of the road, because rural motor vehicles are still chaotic; Don't poke metal objects into the hole of the power socket at home.
