Residents living outside the city should avoid building houses in low-lying areas and areas threatened by landslides, and avoid building houses in places flooded by rivers. Don't artificially occupy the natural flood section of the river. Before and after checking the house in early summer every year, pay attention to the changes of nearby mountains to see if there are signs of cracks and landslides on the mountains.

Urban residents, shopping malls, schools, factories, mines and other enterprises should be familiar with the surrounding environment and bring their own necessary waterproof and drainage facilities, such as canvas, woven bags, sand and gravel, wooden boards, pumps and so on. Pay attention to the forecast of local meteorological flood control department. Shopping malls, schools, squares and other densely populated areas should do a good job of personnel diversion and transfer in time.

Second, after the rainstorm and flood:

When major signs or disasters have occurred, the news will be passed out at the first time, which will attract the attention of the government and strive to control the development and rescue of disasters.

Wait patiently for the river to recede, or cross the river around a distance.

In case of rainstorm and flood, pedestrians should stay away from dangerous areas such as high-voltage lines and electrical equipment, and turn off their mobile phones in case of thunderstorm. Schools should take temporary holidays or stay in school to avoid floods, arrange temporary accommodation and inform their families to avoid accidents on the way to find children. Emergency rescue such as artificial respiration should be given to the drowning person in time.
