When you go to Dandong to eat seafood, it is essential to have a special product of Dandong-the Prince of Dandong. If it is cheap, the seafood in Donggang is the cheapest. It is best to buy raw food, which can be rinsed, boiled and preserved. As for the price, I haven't bought it for a long time, and I'm not very clear. Generally, in this season, a moderate-sized clam weighs about 8- 10 yuan, while scallops and clams are more expensive.
