The Utah Jazz forward is known to the 1.3 billion people in China as "Fan Gu Zai," which, loosely translated, means "Betrayal Skull Dude." Bao says Chinese use "Fan Gu Zai" to refer to those who betray, but "betrayal skull" also refers to a protuberant bone on the front or back of a head.
The betrayal skull reference comes from the Chinese story of Zhuge Liang, one of China's most well-known intellectuals and military strategists. According to legend, before Zhuge died, he said, "Wei will betray the country sooner or later." Wei was a general under Zhuge's supervision. "How do you know?" someone asked. "He has a protuberant bone on his head," Zhuge answered.
So Boozer's nickname of "Fan Gu Zai" is for two reasons: 1. His head is not exactly round, and 2. Chinese fans also believe that Boozer gave his word that he'd return to the Cavaliers in 2004 when he bolted to Utah for more money as a free agent.
