Created in the late 1990s in Colombia by fitness instructor Alberto Perez, Zumba is a high-energy aerobic workout based on dance steps borrowed from salsa, meringue and other dances.

Wang's father, a retired photographer from Nanjing Film Studio, and his mother, a teacher, gave him lots of support.

"My mother dances with neighbors in a park near our house every morning," Wang said.

In 2011, the female lead singer of Phoenix Legend, Ling Hua, contacted Wang and invited him to be their instructor. The duo has also cooperated with Wang to produce an album, which contains 10 remixed songs for fitness dance classes. Wang said he plans to bring the album, to be released next month, to the US.

"His remix took our music to a wider audience and created a new possibility for promoting pop songs," Ling said.

Now, Wang flies between Beijing and the US, giving classes and learning more traditional Chinese dance moves.

"My dream is to have my own dance studio and include more original Chinese music in my classes," Wang said.
