Hello and welcome to the madhouse 
I’ve never been to China, the most exotic I’ve managed was a blagging a short break in Singapore (where my grandparents lived for some time). I did make it out away from the central you-could-be-anywhere-in-the-world parts and did have a “there is no food on sale here that I even vaguely recognise” moment in a food market. A samosa stall tucked away in a corner saved the day.
