He goes under the name Qiu Tian in China and is very likely the first Chinese player of Nigerian ancestry who plays for the National team.
If he's the Chinese Giannis, then Rui Hachimura is the Japanese Gianiss. https://sports.yahoo.com/rui-hachim...-gonzaga-starring-abroad-japan-013427638.html
Giannis is not mixed, though. His family just moved to Greece. Some Chinese articles say that Qiu Tian's Nigerian father played in the NBA in the late 1980s and was 6'3" or so. Who might it be? I can't find such a player. The only Nigerian in the league back then was Olajuwon, no?
