Unless you want to be easily exposed to dangerous elements like gutter oil or fake food, which is prevalent in China, I recommend other food stall cities like Singapore or Taiwan.
And it's funny that you suggested Taiwan, which is the country that gutter oil was first seen: https://en.wikipedia.org/wiki/Gutter_oil#History
And fake food is rampaging through the cities in China, such as moon cake and alcohol. https://www.youtube.com/watch?v=hIpA_RwEtLE
Not sure why you would take Chinese government's word on anything, when they still refuse to accept blame for releasing covid to the world and killing millions, and giving long covid and removing smell and taste for many more.
