At night of March 21 in Beijing time, the 2010 Short Track Speed Skating World Championship entered the last day's competition. In a semi-final of the women's 1000m event, Zhou Yang, China's favorite to win the championship, appeared in the first group. However, when the game had been carried on for half, an unexpected fall of Park Seung-hi from South Korea also entailed Zhou Yang who had almost surpassed her. The two fell down at the same time. Zhou Yang was injured in this fall and left the field.
