The long island sea cucumber and Dalian are still in comparison, which one is better?
I personally feel that Long Island will be better, after all, Dalian industry is more developed, shipbuilding and the rise of the marine oil industry, is bound to destroy the marine ecosystem, pollution of seawater, and Long Island has been in a willing ecological state, in the Yellow and Bohai Seas at the exchange, the water current activity is frequent, an average of six months to replace the water once, the water is more clear.
