I am from Jiamusi, Heilongjiang, and I am engaged in salmon sales. You'd better soak the salted fish in water 10 hour or so, otherwise the fish will be very salty. There are two best ways to eat salmon.

One is steaming:

Cut the soaked salmon into 2-3 cm pieces, then put a little cooked oil in the plate, spread a layer of onion slices and ginger slices, and steam for 25 minutes.

One is frying:

Cut the soaked salmon into large pieces with a thickness of about 1cm, add a proper amount of cooked oil after heating, and fry the fillets with low fire until both sides are red or dark red.

The longest way to eat in Northeast China is to fry salmon.
