Some videos on how Chinese-American dishes are made

I have been eating a lot of Panda Express for lunch because it's cheap. $10, 1 chicken breast, 1 something saucy, rice, vegetables. I also enjoy the Beijing beef and Orange chicken. But now I found a few references on how they are made. It's literally "battered chicken in sugar sauce", so is the beef dish. But I do like their idea of cutting AGAINST the grain, using a bit of baking soda for tenderness, using cornstarch (and maybe egg whites, too) to prevent the meat from drying out in high-heat cooking. I also learned to utilize some vinegar for citrusy flavor, because as I learned from Chinese Cooking Demystified and looking at a lot of sauce bottles, they all shared a lot of common ingredients: water, sugar for sweetness, white vinegar for sourness, flavor (some fruit extract, tomato paste, oyster extract), salt (or soy sauce if Chinese sauce), thickener (corn starch, xanthan gum).
