How to call for help when besieged by a flood?Here's a look at the JOESCO flood wall

  In a hilly environment,no matter they are alone or gather in a crowd,if there is a flood in a high hilly platform or brick-and-concrete residential building with a relatively solid foundation,they can be relieved as long as they keep in an orderly way and wait for rescue or for the mountain flood that rises and falls to recede.If the flood is trapped in low-lying shore and wooden houses,and the communication conditions are available when the situation is critical,the communication tools can be used to report the flood situation and trapped conditions to the local government and flood control departments for rescue.When there is no communication condition, it can make fireworks, wave colorful clothes or call for help in unison,constantly sending out emergency help signal to the outside world for early rescue.At the same time,we should look for larger volume of flotsam and take active measures to save ourselves.
