Eating sea crabs before and after Tomb-Sweeping Day.
Eat river crabs around the Mid-Autumn Festival.
I suggest you buy some in season.
Sea crabs are bigger and easier to eat. Although they lived better, they died without poison.
The crab has a strong flavor, even the male has cream, the white one.
From the perspective of nutritional value, river crabs are also higher, but they can only be cooked when they are alive.
Advantages and disadvantages complement each other.
