Method of making Chinese yam

1. Wash the soil on the outer skin of the yam, peel off the outer skin, rinse it slightly with water, and cut it into slices (if there is oxidation discoloration during peeling, soak the slices in water mixed with white vinegar to prevent discoloration). After soaking the dried fungus, wash it and tear it into small pieces. Wash the colored peppers and cut them into pieces. Soak the goji berries in water for a while<2. Heat up the pot and add a little oil. Add a few slices of garlic and stir fry until fragrant. Then, pour in slices of yam and stir fry.
