You are the first people to eat Mr. Lu Xun's crabs. It means the first person to do something and try something. It shows that a person is brave enough.

Mr. Lu Xun once said: "The first person who ate crabs was admirable, not a warrior. Who dares to eat? " Some people eat crabs and spiders, but they are not delicious, so they will not eat them in the future. We should be very grateful to such people.
