Old Shanghai habits: blowing northwest wind and eating hairy crabs. In recent years, global warming and the cold wave in the south of the Yangtze River have been postponed until around New Year's Day. At this time, the hairy crabs entered the late stage and the output decreased; Not only the quality is low, but also the price is expensive.

"The northwest wind blows and the crab's feet itch" was the local meteorological and phenological experience at that time. Now, scientific breeding technology has made great progress. Judging from the winning of the "National Crab Competition", the best producing area has turned to the lake areas in the middle reaches of the Yangtze River and the lower reaches of the Yellow River. The time to market for high-quality hairy crabs is also advanced accordingly.

In fact, the industrial model in southern Jiangsu has caused great damage to the environment. In the past two years, Taihu Lake has also been polluted, and the production of hairy crabs has been greatly reduced.

There is another reason for blowing northwest wind and eating hairy crabs: after the crabs are cold, the meat quality is tightened and the taste is delicate and more elastic. Now, all our hairy crabs are kept in the cold storage, and the effect is exactly the same. Therefore, every year 10- 1 1 month, hairy crabs are the best.
