With the Mid-Autumn Festival coming, the time for crabs(螃蟹) is around the corner! Dazha Crabs from Yangcheng Lake in China are believed to be the best freshwater crabs.

“They are delicious, because the bottom of Yangcheng Lake is hard and the crabs grow strong by walking on such a hard surface，” said one sales manager in Suzhou.

Li Lei, a crab lover from Beijing, said “It's very delicious! But there are too many fake Yangcheng Lake Dazha Crabs”．

“Maybe the crabs from other regions can appear to be glistening(闪亮的) green back, white belly(肚子) after people wash them, but the golden fine hair on crab claws is still a point of pride and is exclusive to Dazha Crabs from Yangcheng Lake，” said the manager.

The best time for enjoying them is during September and October of Chinese lunar calendar. “When the season for crabs arrives, the Dazha Crabs from Yangcheng Lake fly to various cities so that people's appetites can be satisfied，” said the sales manager. “They are really expensive here, sometimes more than 320RMB/500g, 10% of my salary！” said Li Lei.

Dazha Crabs are usually steamed or boiled for within 20 minutes before they come on the dinner table. They are often enjoyed with vinegar mixed with minced ginger(姜蓉) to add flavor and get rid of the cold. People who are particular about how they eat crabs also need to have high-grade Shaoxing rice wine to warm their stomachs.

There is much work required to eat crabs. So much shell! Most people use both hands and teeth while eating Dazha Crabs. “The eating way is not graceful or elegant，”said Huck. “However, some professionals of eating crabs can use tools to take all the meat out of the crab without damaging a single bite and the crab can be restored to its original shape if the empty shells are pieced together！” said Han Mei, another Dazha crab lover.
