Thirty-three years ago today, on November 5, 1992 (October 11, 1992 in the lunar calendar), 33 people died in a major accident in Henan. Whether the sale of prizes with prizes is considered a legal competition has not been determined, but it did lead to tragedy. On November 5, 1992, two promotional aircraft were flying at an ultra-low altitude in Yuanyang City, Henan Province, and suddenly crashed into the iron pillar above the Yellow River Building. The aircraft crashed, killing 33 people and seriously injuring 46 others.
