If it isn't nailed down, it'll get sold in Zhenhai. Pretty much everything's for sale here. Want pop corn? You can find it. Want chicken legs on sticks? You can get those too. Want Nan bread or hard boiled eggs or any variety of nut you can think of? Yep, got those. How about half a chicken or turkey or duck, or hot dog, or some sort of bready muffin concoction (that taste disgusting)? Yep got those. How about cheese and custard on toast? I know, it's gross -I have no idea what they were smoking when they came up with that- but they do that too.
It's the things they sell that remind me I'm in a third world country if I'm honest. Growing up I learned to mistrust communism through the idea of food lines at supermarkets. If you ever watch shows about living in third world countries (especially in Africa, but more generally I think), it's people scavenging through rubbish dumps and selling crud on the streets that remind you where you are.
Where in the west would you find a guy with his own flat bed truck (and microphone) selling second hand shoes? Or guys selling back scratchers, or clothes horses, or clothes pegs for that matter. I hate to say it, but necessity is the mother of invention, and I've got to hand it to people for getting off their rear ends and doing something about it.
