Might I suggest you look at the following:
Robin Visser and Jie Lu, “Contemporary Urban Fiction: Rewriting the City,” in Kirk Denton, ed., The Columbia Companion to Modern Chinese Literature (NY: Columbia University Press, 2016), 345-54.
It offers a good overview of urban fiction and its major texts, and points to important primary and secondary sources.
