It's summer and it's time to eat barbecued crayfish. It's very good to have a piece of carapace at this time. It's easy to make a delicious one by putting bean paste back on it. But the premise is that you have to choose a good one. You should know that a stinky one can destroy a pot of armour. The following small series will teach you how to choose the armour.

1. There are many people. If you turn the carapace over and over, you should first choose the big one with complete shell and tightly closed shell. It must be alive. Because in the case that everyone is turning hard, the carapace won't open its shell, and it's tightly closed. It needs some force to break it. It must be alive.

2. Standing in the water will stick out a little tongue, touch the tongue from the nail, will automatically retract back, is alive.

3. If the shell is incomplete or damaged; if the shell is completely turned over, the flesh of the carapace will be exposed and the color will turn white; if the carapace is dead in the closed shell, it will be broken off if you do not use force to break it gently, and it will have a strong odor when smelling with your nose. All three kinds of carapace should not be selected.

4. Choose the one with smooth, glossy shell and relatively flat shape.

5. When you buy, you can knock the shell with two armours. The sound is solid and fresh. If there is empty sound, it is mostly dead armor.
