Because there was no flood disaster and no rainstorm and flood. So we don't know enough about disasters. I believe that there will never be a flood disaster in Zhengzhou. That's why I dare. However, unexpectedly, there was a once-in-a-century heavy rainfall in Zhengzhou. Rainfall reached the hourly maximum of land rainfall in China. So this is serious.

It also caused a lot of water in the tunnel, and there was still a lot of silt in the tunnel after several days of drainage. There are more than 200 cars in this tunnel, all of which have broken down. Two other children were killed in the tunnel. Originally, they thought there would be less rain in the tunnel, but the flood in the tunnel killed them.

So it also tells us that when it rains, just wait for shelter from the rain in the high places. Don't wander around. After all, you don't know how heavy the rain will be. So we still need to be on the safe side. It rained too hard this time. Even the best drainage system can't help it. Even if Zhengzhou spends tens of billions to build a sponge city, it can't bear such a heavy rainfall. So there is no way to avoid natural disasters. However, due to problems in the design process. Should be improved. Otherwise, there may be problems.

This lesson is painful. This tells us that there should be no negligence and carelessness in these municipal constructions. There can be no luck. Because these municipal constructions have a service life of several decades. There is no guarantee that nothing will happen in these decades. This is a century-old project, and it must be built well. There can be no security risks. Otherwise, it will be a disaster for a family. Just like these two sacrificed children, even if they are innocent. They have just entered the second grade. How should parents accept the fact of the accident? How do parents live? White-haired people send black-haired people. Therefore, it is necessary to promptly investigate potential safety hazards, and check for leaks.
