The crayfish in Shanghai Danshui is actually a specialty of Hunan! Hunan is called "tasty shrimp", and it must be fresh and spicy to be delicious. The price of lobster depends on the season. I think when it was just produced, the purchase price was more expensive. It is best to come to Hunan market for assessment! When it is cheap, the purchase price is only 2.5-3.5 kg.
The best thing is that the shell is bright red. If it is dark red, it will be too old! Choosing goods is very important!
