Nigerian Adam Musa donates blood to Wuhan Blood Center.

Musa's bond with China was fostered after so many years in the country and it became even stronger in January this year when he won 250,000 yuan ($40,700) in Community Heroes, a televised competition aired by China Central Television, in which people competed to win money for charity.

Musa's prize money will soon be used to build a computer classroom and multi-media lecture hall at the Chunmiao school.

It's not the first time Musa has raised money for the school. In March, 2012 he set up "Adam's special scholarship" there, using 5,000 yuan he won on a similar game show on Hubei TV.

"I just want to give these children hope. Hope is the most important thing in our lives. I don't want them to give up their hope," he says.

While he gives money to the school, Musa himself leads a frugal life, according to his friends, eating simple food in the school canteen, wearing cheap clothes and rarely taking a taxi.

"He has always been a very honest, simple, happy and obliging person since I got to know him a long time ago," says Liang Wei, deputy secretary of the Youth League Committee at Central China Normal University.

Musa recalls his involvement with the school began in May 2010, again during a television show. During the show he found children from the Chunmiao school warmed to him, calling him "black uncle".

The headmaster then invited him to visit the students and some time later, after a long bus ride, the hopeful young man found himself touring the school grounds.
