This gave her the second seed for the final competition bracket in which she faced Albina Kamaltdinova in the first round, beating the archer from Tajikistan 109-102. In the second round, Yun was too strong for Marie-Pier Beaudet (114-107) and via Chen Ling (113-103) in the third round she advanced to the quarter-finals.

In the semi-final however, she was unable to win against the local Chinese favourite Zhang Juanjuan who equaled the newly set Olympic Record by Park Sung-Hyun of 115 points earlier that day.
