My Year Abroad by Chang Rae Lee

Tiller is an average American college student with a good heart but minimal aspirations. Pong Lou is a larger-than-life, wildly creative Chinese American entrepreneur who sees something intriguing in Tiller beyond his bored exterior and takes him under his wing. When Pong brings him along on a boisterous trip across Asia, Tiller is catapulted from ordinary young man to talented protégé, and pulled into a series of ever more extreme and eye-opening experiences that transform his view of the world, of Pong, and of himself.
