On July 20, heavy rains in Zhengzhou, Henan Province, caused severe water accumulation on Metro Line 5, trapping more than 500 people and killing 12 people. Zhang Bingyang, a veteran in 1999, was also trapped on the subway, and after he got out of trouble with other citizens, he participated in the rescue. Zhang Bingyang said that at that time, the fire hose of the subway station was tied together as a safety rope, and he and enthusiastic citizens went into the water to carry the trapped people from the subway to the high place next to the track, and then the crew organized the unified organization to bring the personnel back to the station, which helped about 300 people get out of trouble. Rescuers then rushed to the scene and rescued the trapped people one after another. Zhang Bingyang shuttled through the water-filled carriage and helped search and rescue the trapped people for 5 hours.
