“Dragon boat water” specifically refers to the heavy precipitation that occurs every year from late May to mid-June in South China. Since it often occurs during dragon boat races during the Dragon Boat Festival, people figuratively call it “dragon boat water.” According to the preliminary judgment of the meteorological department, there were 5 large-scale precipitation events in Guangdong Province during the “dragon boat water” period this year. According to information, since the flood began this year, the rainfall in Guangdong has been 2.1 times that of the year. Currently, all parts of Guangdong are making every effort to do a good job of defense.
