Though if you do go back to China, I’d suggest checking out Chongqing — I think it has preserved the street food lifestyle better than Chengdu — people actually do still set up makeshift shacks on the street selling all kinds of things. Chongqing food is different than Chengdu’s “street food”, but at least unlike Chengdu, Chongqing is far from touristy — it’s rather a busy city full of people running around doing business, which attracts comparatively fewer tourists but creates an ideal environment for street food sellers targeting locals. Urümqi and Kashgar in Xinjiang also have excellent street food with both East and Central Asian tastes and plenty of spices.

Taiwan is also another great place for street food — most of its cities have bigger Pasar Malams than Malaysia and well worth checking out, and the culture is being preserved quite nicely there as well.
