This is Lugu shrimp.

The shrimp on the beach in Qinhuangdao refers to Lugu shrimp, also called Luoguo shrimp, and its scientific name is mole cricket shrimp. The appearance of Lugu shrimp is very distinctive. It looks a bit like Pipi shrimp, and its claws look a bit like crayfish. It is still very recognizable. The meat of Lugu shrimp is very tender and chewy. It is a good gourmet ingredient, but it also has a disadvantage. It has a large intestine, which is difficult to clean and handle. Lugu shrimp not only tastes great, but there are also many ways to eat it. The most classic and simple one is spicy stir-fried Lugu shrimp.

You only need to aim the tube at the small air holes on the beach, pump hard, and throw the sand to the side. You can usually get at least one "Lugu shrimp". The most I pulled out was 8 Lugu shrimps at one time.
