Steps:

1, prepare two big fish and salt.

2. Scrape the scales and wash them, and cut the opening from the fish tail to the back with a sharp knife.

3. Open the belly of the fish, take out the internal organs of the fish, cut off the head and wash it.

4. Rub two layers of salt inside and outside the fish with salt and put it into the basin. After two days, close the fish and marinate for four days before drying.

5. Cover the fish with iron wire or cloth, spread the fish out with chopsticks or bamboo sticks and hang it in the outdoor sunshine.

6. Sun for 4 to 5 days until the fish is 70% dry. If it rains on cloudy days, hang the fish in a ventilated place to dry.
