Of course, the domestic sea cucumbers are the best from Liaoshen and Yantai, Shandong Province. The southern sea cucumbers are all artificially cultured from sea cucumber seedlings introduced from the north, and their nutritional value can't be compared with that of Liaoshen in the north. The best in Liaoshen is pure light dry sea cucumber, and others are salt dry sea cucumber. There is no way to compare sugar dry sea cucumber with pure light dry sea cucumber.

Overseas, the sea cucumber in Hokkaido, Japan is also quite good, as well as Russian red ginseng and Arctic ginseng, which are not inferior to Liaoshen.
