There are about 280 species of fish along the coast of Dalian, mainly including small yellow croaker, hairtail, cuttlefish, cobblestone and six-line fish. There are about 400 species of marine invertebrates, among which shrimp, shrimp, jellyfish, conch, sea red, oyster and so on have high economic value. All of the above are seafood that is a specialty of Dalian. In addition, I can't help but mention Liaoshen.

Liaoshen refers to Liaoning sea cucumber, which is the first of the traditional delicacies "eight treasures of the sea" and the main ingredient of the famous "Buddha jumping over the wall", invigorating qi and nourishing blood, consolidating the foundation and cultivating the yuan. 1972, US President Nixon arrived in Beijing, and Premier Zhou Enlai hosted a state banquet named Liaoshen. Generally speaking, the origin of Liaoshen refers to Tieshan, Beihai and Shuangdao Bay within the boundary between the Yellow Sea and Bohai Sea in Lushunkou, Dalian. There are many disputes among the people, and most scholars prefer Beihai Village, a frozen town thousands of miles away.
