Wow, food in China can be so hyperlocal that I thought surely this won’t include stuff that’s not know outside China, like Guilin Noodles, but its there just under a different name than what I expected.
In particular, going to Hangzhou and trying the food there opened my eyes to how varied Chinese food is. There were a lot of lightly cooked vegetables and thinly sliced meats with subtle flavoring and sauces, the opposite of what I thought of saucy heavily cooked stir fry.
