You ask what changed? You seriously underestimate the kind of China has gone through. China over last 30 years has seen changes that were monumental. Literally, millions and millions of people can now feed themselves with 3 meals a day. China has never been as prosperous as this before, and things are getting better.
Keep in mind that all the horrible things you mentioned are not unique phenomena historically. All those things were there in abundance long before industrialization took place in China. Therefore, these phenomena are not results of industrialization. In fact, more industrialization, more modernization, freer market, removal of notoriously bureaucratic China's communist government regulatory hurdles are what would make China prosperous.
