Shit, I learned how to add fish to diced oil cake rolls in Cangzhou, Hebei Province, as well as braised pork rolls, roast duck rolls, chicken fillet rolls, duck sausage rolls, squid rolls, chicken chops rolls, beef rolls, tripe rolls, and how to make cakes, sweet noodle sauce and garlic sauce. You can try to learn any kind of food first. If it's not delicious, you don't have to learn. If you don't line up, you don't have to learn!
