It is suitable to eat sea cucumber in autumn and winter. But in the past, it was said that autumn and winter were the most suitable, mainly because of the limited harvesting and storage technology in the past. Sea cucumbers crawl into the mud in summer and sleep in summer. Only in late autumn and early winter, when the temperature is suitable and the sea cucumber is fertile, can it be harvested. In addition, the backward processing methods in the past could not preserve sea cucumbers for a long time, and they could only be eaten in autumn and winter. So, in fact, Shanghai ginseng can be eaten all year round.
