A man in his 50s was rescued by the South Korean Coast Guard after becoming stranded in a tidal flat near Mosando Island in Hongseong, Chungcheongnam Province. The man was engaged in "haerujil," the practice of collecting shellfish by hand, when he became trapped by rising tides. Authorities were alerted and dispatched a rescue team to the location. The man was successfully rescued and is reported to be in stable condition. This incident highlights the dangers associated with tidal flat activities and the importance of being aware of tide schedules. Coast Guard officials urge caution when participating in haerujil, especially during periods of high tide.
