So a certain Liu Feng, a multi-talented video editor from Beijing working at W+K Shanghai, traveled up to northern China over CNY to discover the secret behind a popular web video featuring a Chinese beat-boxing virtuoso.

What he found is hinted at in the trailer above. Yanji, a city of just over 400,000 people located near the border to North Korea, is a virtual breeding ground for fledgling Chinese beat-boxers. Taking elements from popular Korean, Chinese and American culture, Yanji's b-boys and b-girls are carving out a style all their own.

Shanghaiist will keep you informed as to Liu Feng's plan to turn the trailer into something more substantial. In the mean time, a little something else to whet your appetite ... after the jump.

Also from Liu Feng at W+K, enjoy...
