Li, 23, shed tears of joy after securing her first Paralympic Games gold medal.
"It means so much to me," said Li, who has visual impairment. "I have been with my coach Zhang Guifu for seven years. He is like a father to me. That is why it was so emotional. He taught me everything. I owe this gold medal to him."
And in shooting, China's Dong Chao successfully defended his Paralympic 10m air rifle standing SH1 title by holding off Abdullah Sultan Alaryani of the United Arab Emirates.
Dong secured the gold medal with 205.8 points, beating Alaryani by just 3.2 points. Korea's Kim Suwan took bronze with 181.7 points.
