Even though you can find many of the same products in a chinese supermarket and a western one it is/was still a big adjustment for me!
The three chinese food staples
Oil...chinese people stir fry everything! The amount of oil in chinese dishes is something that took me a long time to adjust to
RICE. Every meal is served with rice
I tried to find brown rice but could only find imported brands in the imported aisle...kinda weird!
Produce: (Prices are per 500 grams)
Beans (they don't sell any canned beans--it took me awhile to find these!)
It is very rare to see any pre-cut veggies
It kinda looks like an outdoor street market
Some stores have precut fruits--usually cantaloupe or melons
There's many tropical fruit here that I love...dragon fruit, papaya, lichee, jackfruit
After you bag your produce or beans or sometimes even eggs you must take it to the weigh station. They weigh it and put a sticker on it that tells you how much it costs. If you go to the checkout without a sticker they cannot check it out.
Chinese medicine//tea (the first few months i was here i could not find decaffeinated tea! I used to drink a lot of apple cinnamon tea and lemon ginger--I found lemon and ginger in these baggies and have started to make my own tea)
Freezer aisle--Lots of jaiozi--dumplings, ice cream, and meat rolls
and dried fish...just imagine how this smells. ewww
Meat and poultry...Theres a saying that Chinese people eat anything with four legs besides a table
They do not let any part of an animal go to waste
VERY fresh fish
The selection of soda...pepsi, diet pepsi or sprite, coke, diet coke, or 7 up
And the check out stand...batteries and condoms
