2. Stir-fry the fat beef with shredded onion, pour in soy sauce or oyster sauce, a spoonful of sugar, and a proper amount of salt, and stir fry quickly. Finally, add the tiger skin pepper and stir-fry until the fat beef is cooked. If you don't want to stir-fry together, just stir-fry the fat beef and put it on the tiger skin pepper.
3. After the broth is boiled, add the shredded tofu and cook it out. Add the fat beef roll, a spoonful of salt and half a spoonful of soy sauce. Boil the fat beef until it is medium-cooked, throw in the chopped leeks, and take out the fat beef when it is cooked. The leek will taste very old in the morning. If you can't grasp the medium-cooked, wait until the fat cow is cooked before putting the leek. Don't throw the leek into the pot for more than 30 seconds.
