China's Quan wins gold on 10-meter platform at Paris Olympics
Quan set the tone on her first dive, recording a perfect score of 10 from all seven judges. The dive was a forward 3½ somersaults, setting off wild cheers among a venue packed with Chinese fans.
Chen Yuxi of China took silver, a repeat of their finish three years ago at the Tokyo Olympics.
Kim Mi Rae of North Korea won bronze, adding to the silver medal she claimed earlier in women's 10-meter synchronized, which was the country's first medal in Olympic diving.
Quan scored 425.60 points on five dives, compared with 420.70 for Chen and 372.10 for Kim. Caeli McKay of Canada was fourth with 364.50 points.
The two Chinese women teamed up earlier to win the 10-meter synchronized in Paris.
China is aiming for an unprecedented sweep of the eight diving golds. The Chinese so far have won five golds after winning the four synchronized competitions in the opening week of the Games.
Quan and Chen had big leads over the field after the preliminary round on Monday, but those scores do not carry over to the final. It didn't matter. They piled up the same margin there.
