China is one of the few countries in the world with a wide variety of natural disasters and the most severe disasters. Throughout the 5000 year history of Chinese civilization, humanity has never stopped fighting against natural disasters. According to relevant data, floods account for 40% of the total natural disaster losses in China every year, and more than two-thirds of the country's land area is threatened by floods; Droughts occur frequently in Northeast, Northwest, North China and other regions, while severe droughts occur occasionally in Southwest, South China and other areas. Floods and droughts are currently the most frequent natural disasters in the world, but people's awareness of natural disasters is insufficient, and there is a lack of advance prevention measures and self rescue methods. The emergence of the China Flood Control and Drought Relief Material Network (formerly known as the China Flood Control and Emergency Relief Material Network) can guide and solve these problems we encounter.
