1, first cut the knife from the fish's back and split the fish in two (the fish's stomach was not cut off).
2. Then wash the cut fish, then rub salt with your hands and massage.
3. Turn the fish over and massage it with salt.
4. Then put salt on the remaining fish and leave it for an hour to make the salt taste.
5. Then insert a bamboo stick under the fish head and put the fish flat. When dried, the fish won't stick together.
6. Finally, it will be good to bask in a sunny place for 3-4 days.
