Things I've noticed about the particular Chinese food culture of my girlfriend: Ginger goes in Chicken soup. Garlic does not. Broccoli is only cooked until bright green. Black pepper is used, basically never. All vegetables are to be rinsed, even the things in Trader Joe's packages that say "Triple Washed, Ready to Use." Almost no claim on the package should be trusted, ever.
Meat is always well cooked. (And there are plenty of ways to make meat very tasty without having it be super-rare.)
