Gui, who is from the southern city of Nanning, wants to make it clear that it's different in her case.
"I'm against these players who go to the Olympics to play for a country that they've never even visited. Sometimes then don't even know anything about the country. This is just wrong," she said, speaking nearly perfect Portuguese.
Hoyama said most Chinese players are older when they earn a new citizenship and usually only travel to their new country during competitions, which is not what happened to Gui, who has returned to China only a few times but still talks to her parents almost daily on the Internet.
"It wasn't easy to leave home as a kid, it wasn't easy to change countries," Gui said. "But it was all worth it, definitely. The most important thing is that I'm doing something that I like, playing the sport that I like here in Brazil and going to my first Olympic Games."
