"It was very exciting and it's a very emotional moment because in this tournament, every player is really tough," Wang said. "It's so difficult to be here on the last day. I'm happy to be here.
"I wanted a title from the first day, even when I started tennis. It was really a dream for me. I think there's going to be bigger tournaments, tougher matches waiting for me and I'm just trying my best like I did this week."
China last hosted a WTA tournament in 2019, before the COVID crisis wreaked havoc on the global sports schedule.
The WTA later suspended its tournaments there after former doubles world number one Peng Shuai said in a now deleted 2021 social media post that a former Chinese government official sexually assaulted her.
Peng then briefly disappeared from public view and later denied making the accusation, sparking an international outcry over her safety.
The WTA was widely praised for suspending tournaments in China but reversed its decision in April.
