Beyond their wildest dreams, Team China won gold in the women's 4x200m freestyle, setting a new world record time of 7 minutes 40.33 seconds.
Just an hour earlier, Zhang Yufei, one of the swimmers on the 4x200m team, dominating in the women's 200m butterfly,
finishing more than a body length ahead of two Americans, and setting another Olympic record.
Double golds and a couple of records have made Zhang a breakout swimming star at the games.
And some Chinese athletes made history at the games even without taking any golds.
Su Bingtian became the first Chinese athlete to qualify for the men's 100m final, also breaking an Asian record.
The Chinese women's Rugby Sevens team reached the final eight, the best result for China in the event.
China's 3x3 women's basketball team won bronze, marking the first time in 29 years China has been on the Olympic basketball podium.
And one of the youngest Olympians, 16-year-old Zeng Wenhui,
became the first Chinese skateboarder to make a games appearance in the women's street skateboarding final, and with skateboarding making its Olympic debut to boot.
In the men's double sculls rowing final, China took the silver medal, marking the first Olympic medal for an Asian country to rowing.
Beside the breakthrough, there were also some regrets.
China's women's volleyball team lost the chance to compete in the quarterfinals after losing to the United States, Russian Olympic Committee and Turkey,
marking the first time in 37 years China has failed to reach volleyball quarterfinals in the Olympics.
And at the men's gymnastics individual all-around final, Chinese male genius Xiao Ruoteng was unable to grasp all-around gold,
claiming silver after Japan's Daiki Hashimoto leapt up the standings in the final rotation.
And more regrets, Chinese pair Xu Xin and Liu Shiwen lost the table tennis mixed doubles gold medal, being narrowly defeated by Japan's Jun Mizutani and Mima Ito.
Yet whatever the results at this year's Olympics, many Chinese netizens say the athletes are still the pride of the nation.
