I can't even remember where I first saw this clip, but it's from a Cuban television show called "Para Bailar Casino." This particular style of Salsa dancing has usually been unique to Cuba and Miami, but is starting to spread slowly to wherever Salsa dancing happens around the world. So, it's still fairly rare to see a Chinese guy (or any non-Cuban) who is this skilled at casino style Salsa. He has plenty of moves but, more importantly, he captures the fun spirit of the dance. The crowd obviously responds well, as you see them stand up and cheer!
In the video clip, there is a caption saying the name of the Chinese man is "You Fei Huo," but apparently his real name is Yaofei Huo. For us English speakers, he goes by "David" Huo. :-) He teaches in Beijing, China at a place called Casa De David, and his website is:

The song to which they are dancing is called "Esto Te Pone La Cabeza Mala" by Los Van Van.
