As the saying goes, "Oranges are oranges when they are born in the south of the Huai River, and they are hedges when they are born in the north of the Huai River." A Huaihe River, so that the sweet and sour tangerine in the south has become the obscure and difficult to swallow Hovenia in the north. This also fully illustrates the importance of the place of origin. Consumers in the purchase of sea cucumbers, merchants will say that their sea cucumbers are the best, the source of the most authentic sea cucumbers, Dalian, Changhai, Beihai, Roe deer Island, Long Island, etc., there are even more straight straight to the point: "My Sen is Shandong, but who says that Shandong Sen must be inferior to Liaoning Sen? The most important thing to remember is that the sea cucumber is the most authentic one.

Liaoning sea cucumbers, referred to as "Liao Shen", as a symbol of high quality of sea cucumbers, are mainly produced in the Bohai Sea waters of Dalian. Because of its wide harbor and deep water, the water quality is pure, and the sea cucumber grown here has thick meat, many thorns, sleeps in summer and hibernates in winter, has a long growth cycle, and is rich in nutrient accumulation. In the Ming Dynasty, "The Materia Medica from the New" pointed out long ago: "Sea cucumber, produced in the Liaohai Sea is good."

Shandong sea cucumber, also known as "Lu ginseng", is mainly produced in the three places of Qing, Yan and Wei, which is also one of the most important sea cucumber production and processing bases in China. The growth environment of the sea cucumber is not much different from that of the Liao cucumber, and it takes 3-4 years for an individual to grow into a sea cucumber. The sea temperature near Dalian, Liaoning is low and the sea water is deep, so the growth speed of sea cucumber is slow, but in the process of growth, there are many nutrient enrichment, so the sea cucumber's body wall is fat and thick, the spines of the meat are full, and there are fewer impurities in the body, so the nutritional value of the sea cucumber is higher. The Shandong sea cucumber is not so different from the Liaoshen in form, but it is more or less a chip away from the Liaoshen in terms of nutritional value.

Fujian is the main place of origin of sea cucumber in the south, but because of the environmental requirements of the growth of sea cucumber, so Fujian sea cucumber is mostly "north cucumber south", some "orange born in the north of Huaibei for Hovenia", high quality cucumber seedling from Liaoning and other places to introduce into Fujian, and then feed the local natural environment and a large number of artificial feed, so it is not a big difference. In the local natural environment and a large number of artificial feed feeding, the growth cycle of sea cucumber which originally needs 5-7 years to grow into is shortened, and only about 1 year can be harvested, the yield is big and the harvest is fast, so the nutritional accumulation and the taste are far inferior to the sea cucumber in the north.

There are very few countries in the world that consume sea cucumber, only a few East Asian countries such as China, Japan and South Korea, and European and American countries do not consume sea cucumber. Imported sea cucumbers mainly come from Japan, North America, Russia and other places. Due to the big difference between the categories of sea cucumbers and Chinese sea cucumbers, they are not accepted by consumers at the beginning of the domestic market, but with the propaganda, the nutrition of imported sea cucumbers is gradually recognized, but due to the high price, the number of people who choose them is still relatively small.

Domestic sea cucumber has many origins, and the price is different. Generally speaking, domestic sea cucumber is the best in Liao Sen, followed by Shandong and Fujian. However, you can't generalize and make a sweeping statement.
