River fish is the fish in the creek, pollution-free wild fish. They are usually dried and stored over fire. In rural areas, they are only taken out to entertain guests when they come.

A kind of fish raised in Nanxi River is called Xiyu. It grows in a relatively clean environment and tastes delicious. In rural Yongjia, the amount of stream fish is now small and the price is firm. Baked raw dried fish costs at least 70 yuan per catty, and larger ones cost 80 or 90 yuan per catty. There are many fake dried fish on the market now.
