The fans have been flocking to Beijing Olympic Park for this week's Premier Mandatory-level China Open.
From the 15,000-seat stadium court to the 10 outside courts, fans are getting their fill of tennis.
But the fans aren't just there to watch their favorite men's and women's players go to battle.
They're also coming out to put forth their support - and help inspire - those favorite players.
Chinese No.1 Li Na - also Asia's first Grand Slam champion - has definitely had her share of support.
Li became Asia's first Grand Slam champion at the 2011 French Open and is currently No.5 in the world.
She has also reached two more Grand Slam finals, at the Australian Open in 2011 and this year.
Li has not won the China Open before but has reached the semis twice since it became Premier Mandatory.
This year Li made the quarterfinals but was ousted in three sets by a very in-form Petra Kvitova.
Svetlana Kuznetsova - the only two-time China Open champion before this year - also had her support.
The fans have been loving their doubles, too - here are some Peng Shuai and Hsieh Su-Wei fans...
And any former champion at a tournament will have lots of support, like 2010 winner Caroline Wozniacki.
The cheering section of Sabine Lisicki, who has had some great matches against Li in the past.
Serena Williams is cheered on all over the world - one of her biggest fans is sister Venus Williams.
Williams is a one-time winner here, having conquered the inaugural edition of the event in 2004.
Kvitova dashed Li's hopes but her own hopes were dashed in the semifinals against Jelena Jankovic.
Jankovic also won here once, the last year before it became a Premier Mandatory event - 2008.
Williams and Jankovic will play for the 2013 title on Sunday - Williams leads the head-to-head, 6-4.
Jankovic is one of just two active players to beat Williams four or more times - also Venus Williams.
One of them will join Kuznetsova as a two-time China Open champion on Sunday night... don't miss it!
