The Chinese community is particularly huge, with over 400,000 people of Chinese ancestry here. And anyone who has visited cannot have missed the bright lights of Chinatown, which is also one of the few spots open to grab a late-night meal.
So it’s unsurprising to see and hear a lot of backing for Zheng tonight.
While Rod Laver Arena has thinned a tad since Sabalenka’s match against Gauff, there are lots of Chinese fans who are vocally backing the 12th seed and enthusiastically waving their Five-star Red Flags.

That's brave from Dayana Yastremska. She helps the ball kid to pick up a creepy crawly and get it off the court.

American former world number six on BBC Radio 5 Sports Extra and BBC SoundsYou don't get through all the matches that Dayana Yastremska has gotten through in this event without understanding how to fight back, how to compete, how to turn matches around, how to turn sets around.
She's used to digging in and some of that becomes more automatic in these moments.

The world number 93 works Zheng Qinwen from one side of the court to another and the Chinese 12th seed can't keep up.

Dayana Yastremska is annoyed with herself for not getting the hold over the line, smacking the ball into the net.
She'll have another chance, though, as Zheng Qinwen sends the next point wide.

There was no holding back from Dayana Yastremska in that last game. She's a set down and knows she's got nothing to lose.
The Ukrainian qualifier goes big with a delightful forehand straight down the line, much to the appreciation of the Rod Laver Arena crowd.
However, Zheng Qinwen isn't backing down either as she brings up deuce with a cross-court winner.

The crowd in Rod Laver Arena are doing their best to help get Dayana Yastremska back on track.
She offers an apology to Zheng Qinwen after getting lucky with a net cord, but I doubt she'll care that much.
The Ukrainian qualifier has two break points.
