Ocean swimmers have been urged to avoid jellyfish following the death of a woman who was stung by one last month.

On July 26, the 47-year-old woman traveled to Beidaihe resort in North China's Hebei province to celebrate her daughter's graduation from a university. The next day, the woman and a friend were stung on the beach.
