When did Sun Yingsha ask Fan Zhendong for her autograph?

When did Sun Yingsha ask Fan Zhendong for her autograph? On August 4th, it was reported that at the Tokyo Olympic Games, Sun Yingsha, a 20-year-old table tennis player, swept Mikei Ito, a Japanese elder sister, in the women's singles semi-final, which left a deep impression on everyone. Interestingly, when he idolized teammate Fan Zhendong, the little devil's actions made people laugh. However, it should be Sun Yingsha's friend who wants Fan Zhendong's autograph, so the little devil asks Xiao Pang for his autograph. She is not a real "fan" of Xiao Pang.
