On the shooting range, student athlete Yang Qian won her second gold medal at the Tokyo Olympics together with Yang Haoran in the 10-meter air rifle mixed event. Pang Wei and Jiang Ranxin won gold in the 10m air pistol mixed competition after showing true team spirit.

Both the gold medals are the first China has won in the two events at an Olympics. Yang Qian became the first shooter representing Team China to claim multiple gold Olympic medals after winning the women's individual 10m air rifle on Saturday.

"I am very happy. It is special to win an event like this," Yang Qian said, adding that "I thank my country for helping me and giving me all the support."
