“It is better to be on guard than to be on guard against anything unexpected”, which is a kind of responsibility. We are currently in the main flood season, with frequent, frequent and repeated occurrences of extreme weather. The flood control situation is very severe and the situation is very complex. The more complex the situation, the more scientific methods must be emphasized, the more important must be to grasp the key of "prevention", and the more important must be to highlight the key point of "prevention". If flood prevention and disaster relief is the battlefield for mankind to fight against natural disasters, then "prevention" is the first "battle"; if flood prevention and disaster relief is an examination room to test the original mission of party members and cadres, then "prevention" is an "examination question." To tighten the string of flood prevention at all times, we must strengthen the main responsibility of "prevention", build a strong dam of "prevention" responsibility, and put the safety of people's lives first and implement it. "It is better to be on guard than to be on guard against anything unexpected", which is a kind of responsibility. The responsibility of "prevention" is reflected in the responsibility of specific people and specific matters. Flood prevention is no small matter, and there is no room for carelessness or slackness. To answer the question of "prevention" well, we must not only be mentally prepared and resolutely overcome paralysis and fluke mentality, but also be prepared for plans, teams, materials, and flood storage and detention areas. To fight the battle of "prevention" well, the key is to have "ears and eyes", and do a good job in forecasting and early warning. We must pay special attention to the application of new technologies such as drones and 5G, and use high-tech means to accurately monitor and quickly analyze and judge, so as to improve the efficiency and effectiveness of "prevention" ability; we must keep a close eye on important parts, important facilities and weak links, and carry out comprehensive, multi-level, network-type inspections and inspections. Forecast and early warning, all-weather duty, dike strength, dike patrol team, inspection frequency, hidden danger investigation, etc., a We should focus on each link, detail by detail, grasp the early and small, grasp the small, and make sure the "prevention" is foolproof, and do our best to "shield" the danger from the masses. Life is greater than heaven, once lost, everything is lost. Emphasizing that "it is better to be on guard against all odds than to be unprepared for anything", in the final analysis we must adhere to the supremacy of people and life, enhance the awareness of danger, establish bottom-line thinking, start from the most unfavorable situation, and rather believe that there is something than that that there is nothing. , I would rather believe in the big than the small, think about all the problems that should be thought about, do all the work that can be done, take the most adequate defensive measures, build a strong safety line of defense, and ensure a safe flood season.
