Ndesandjo, 48, lives in Futian, Shenzhen, with his wife, Liu Xuehua, a Henan province native and his partner of a decade. The pair met in a tea shop when Ndesandjo was an impoverished English teacher. He had emigrated to China in 2003 from Orlando, Florida. Having lost a well-paid job in the telecommunications industry in the post-9/11 economic slump, he wrote to the director of a mainland teaching project he'd read about in a magazine, asking for a job.
"He said, 'You're obviously too qualified.' But I really wanted to explore China."
Ndesandjo expected to stay for three months. Twelve years later, he is fluent in Putonghua, proficient in calligraphy and has no plans to leave the country. Long-standing rumours tell of him running a barbecue restaurant in Shenzhen, but he laughs them off.
"I'm a vegetarian," he says.
What he does run is a foundation that helps children in need, while also teaching piano to orphans, raising awareness of domestic violence and heading up two consulting companies that assist American investors entering the Chinese and Kenyan markets, and those looking to go in the other direction, one registered on the mainland, the other in Hong Kong.
