Hairy crabs will molt 10 times in their lifetime, and each molting represents every growth. June Yellow is the last molting of hairy crabs before they enter maturity, and it is also the stage when hairy crabs enter youth from teenagers.

June yellow is a male crab, especially the male crab that was shelled for the last time. The crab's belly is dark brown and soft to the touch. The weight of June yellow is generally about 2 Liang, which has the characteristics of crisp outer shell, soft inner shell, heavy fishy smell and plump meat.

The biggest difference between hairy crabs and June yellow lies in gonads. Although people eat June yellow, they can't eat the gonads of crabs, which is what people call crab paste.
