Yu Sannan's champion crab is by no means in vain. Since 2012, Yu Sannan is the only one who has been selected as a "crab champion" by the Suzhou Yangcheng Lake Hairy Crab Industry Association, and has won the title of "Suzhou Farmer Expert" by raising crabs, and is also the only crab farmer who has been rated as one of the "Top Ten Outstanding Farmers" by Jiangsu Province. The brand was jointly launched by Yu Sannan and Benlai Life Network in 2013, and it is another agricultural product brand of Benlai Life Network after "Chu Orange", "Liu Tao" and "Pan Apple", and it will be on the best-selling list of Benlai Life Network every autumn.
 
As a pioneer of China's fresh new retail, it has built 60,000 square meters of professional cold storage in 7 cities in Beijing, Shanghai, Guangzhou, Shenzhen, Rong, Hansu, covering the main first- and second-tier cities with strong consumption power for hairy crabs. In addition, Benlai Life Network has 109 fresh food distribution cities across the country, and the goods are distributed by its own logistics "micro special school", providing cold chain logistics services for tonight and the next day, which can link hairy crabs directly from farmers to the table.
 
Yu Sannan, the champion of crab farming, began to breed hairy crabs in 1996, because he dared to be the first to innovate breeding technology, in 2002, when the area of the purse seine was reduced for the first time, each individual farmer was only allocated 30 acres of water surface, but Yu Sannan was allocated 264 acres, in order to make a demonstration for Yangcheng Lake crab farmers. In recent years, Yangcheng Lake has suffered from deterioration in water quality again, and Yu Sannan has innovated the "diagonal farming method" for this purpose, dividing the square water area of crab farming into four areas with a diagonal, and rotating breeding in different areas every year to achieve another form of "fishing moratorium", and even attract the attention of the local aquaculture department.
 
In order to improve the problem of unsuitable water and soil after the crab seedlings were transported to Yangcheng Lake, he selected the strong male crabs of Yangcheng Lake and the wild female crabs in the Yangtze River basin to mate and lay eggs, and completed the desalination and cultivation in the inner pond, and the survival rate of crab seedlings was as high as 60%. In addition to 50,000 adult crabs every year, 5 million crab seedlings are sold to crab farmers in Yangcheng Lake, which is also an important input for Yu Sannan, and about 300 of the 1,800 farmers in Yangcheng Lake are his crab seedling customers.
 
Avoiding the long-distance travel of crab seedling time, Yu Sannan's hairy crabs can grow for more than 18 months in Yangcheng Lake, and experience a total of 23 molts.
