A man was safely rescued after floating at sea for almost two hours in east China's Yancheng city. He went beachcombing early in the morning but got trapped by sudden rising seawater. Using a plastic basket for buoyancy, he stayed afloat and waited for help. Rescuers used drone thermal imaging to locate the man quickly and picked him up by boat. Fortunately, he suffered no injuries. Authorities have reminded people to check tide times carefully before going near the sea.
