According to legend, thousands of years ago, there was a fierce beetle with eight legs and two claws in the rivers and lakes. Not only stealing rice, but also catching people with claws, so it is called "catching people and insects". Later, Dayu went to the south of the Yangtze River to control water and sent a strong man, Plo, to supervise the work, which seriously hindered the project. The PLO figured out a way to dig a trench around the city and fill it with boiling water. People and bugs came, fell into the ditch and burned to death. The scalded insects were flushed red and gave off an attractive fragrance. The plo cracked its shell curiously, and the smell became stronger. I got the nerve to take a bite, but it tasted delicious, better than anything else, so fear of pests became a household name. In order to thank Plough for being the first in the world, we added the word "worm" under the word "Xie", which means that Plough conquered the worm and was the first person to eat crabs in the world.
This is a legend, there is no source.
At present, the earliest clear record of "the first crab eater in the world" can be found, and only the Cave Ghost of Hanwu written by Guo Xian in the Eastern Han Dynasty is referred to as "Cave Ghost" for short. The third volume is: "The country of good karma tasted a crab, which was nine feet long and had four claws, so it was named Hundred-legged Crab. Boiling its shell is better than yellow glue, which is also called chelating glue, which is better than the glue of chicken beak. " Most of the strange things in Dong Ming Ji are nonsense, but their words are gorgeous and some materials have certain academic value, so later scholars are willing to quote them. Yamahara is one of the western countries. According to the Records of Foreign Bodies in Lingnan quoted in Taiping Magnolia, "If you try to swim in the sea, you will get an island with lush trees. You are a ship climbing a cliff, tied to the water. I can't cook for the time being, but the cable suddenly broke and I can go there. Look carefully, the big crab is also there. " Therefore, it can be seen that the crabs that China people eat for the first time may be sea crabs. Hundred-legged crab may be the literary image of sea crab. As for whether Emperor Wu of the Han Dynasty was the first person to eat crabs in China, I'll just say, you might as well listen.
