You can eat it directly. If you think the salty flavor alone is not good, you can use soy sauce, vinegar, sugar, ginger juice (to remove the stink), monosodium glutamate (MSG), and sesame oil to make a sauce and pour it on the thinly sliced preserved beef (mutton).

Also, directly cut the preserved beef (mutton) into slices or small pieces, and add them to hot cakes (steamed buns) for direct consumption, which is also delicious.
