2. Add soy sauce, vinegar, cooking wine, salt, sugar, pepper, allspice powder and egg liquid, mix well, then cut some ginger slices and garlic slices and put them in for pickling.
3. Cover with plastic wrap and marinate in the refrigerator for more than two hours. The longer the pickling time, the better.

5. Stir the sliced meat and sweet potato powder evenly.
6. Pour more oil into the pot to heat it up, then add the sliced meat and start frying.
7. Fry until the meat slices are golden yellow, and then remove them.
