The seemingly delicate jellyfish is actually not easy to mess with. If provoked inadvertently, it may throw its toxin-containing tentacles at people. Doctors remind that a large proportion of jellyfish stings that occurred in the past were caused by people actively provoking jellyfish. From July to October every year, most jellyfish will surface, so this period is also the peak period for jellyfish stings. Doctors remind citizens and tourists that it is best to avoid jellyfish when bathing in the sea during hot weather. If you are stung by jellyfish, you can borrow alum from the nearest fisherman to apply it. If you have symptoms of organ pain or breathlessness, it is best to go to the hospital immediately for treatment.
