The only Chinese representation left in the Women's singles event, Wang Qiang, has reached the second round of the US Open.
The 23-year old cruised past Greece's Maria Sakkari in straight sets, 7-5, 6-2.
She'll be up against Barbara Strycova of the Czech Republic in round-2.
Second seed Simona Halep of Romania is through after her opponent, a qualifier from New Zealand, retired due to injury.
"So here I came very confident, of course, because I feel the game, I feel pretty well the game, but still I have no expectations. I play better when I don't think about results. I play better when I feel a little bit of pressure, because I'm very focused always. Now it's in the middle. I feel pressure, but still I have no expectations. So I feel great, and I just want to take match by match."
Meanwhile, 6th seeded Lucie Safarova is the latest seed to be given an early exit from the US Open, losing to 37th-ranked Ukrainian Lesia Tsurenko 6-4, 6-1.
"I mean it's very disappointing because obviously I wanted to be 100-percent for the US Open, for the Grand Slam and it's very unfortunate that it happened at the last minute like that. But that's sport. It happens. Injuries come and go. It's just a bad timing. And Lesia played very well today and even though I tried very hard, if you are not 100-percent you just cannot, cannot win these days."
Over to the men's side, five-time champion Roger Federer has advanced to the second round, beating Argentina's Leonardo Mayer in straight-sets.
Marin Cilic has started the defence of his US Open title with a straight-sets victory against the 94th-ranked qualifier Guido Pella.
Other competitors like American John Isner, Dominic Thiem from Austria and Andrey Rublev of Russia have also progressed.
