Teenage volunteers learn to perform CPR during a water safety and life-saving training session yesterday. The training session, organized by Red Cross Society of China Shenzhen Branch, aimed to provide important tips and guidelines on keeping young people safe in, on, and around the water. According to the World Health Organization, around 372,000 people die worldwide from drowning each year. In recent years, drowning has become a top cause of accidental death among juveniles and teenagers in Shenzhen. The period from July to August is the peak season for drowning in the city.           Sun Yuchen
