The first one is hairy crabs! Speaking of hairy crabs, the first thought that flashed through everyone's mind may be expensive! Indeed, hairy crabs are huge and delicious. With the hype in recent years, they once became "luxury goods", and the price was calculated according to two. A few years ago, five or six hairy crabs sold for 7800, all at 1000, which can be said to be comparable to the luxury of abalone. But many people may not know that in the past, hairy crabs were eaten by the poor. At that time, there was not enough food, so many people could not eat. People with poor family conditions directly ate hairy crabs! In our grandparents' generation, we should be deeply touched by this situation, but who would have thought that now that everyone's economic and living conditions are good, everyone can eat enough, hairy crabs have become luxury goods, and prices have been rising all the way!

The second kind is scaleless fish! Before the 1980 s, many people rejected this kind of scaleless fish, such as turtles, eels and so on. Of course, it may also be because the whole society didn't have such complicated cooking methods at that time, and the taste was slightly worse, which became the food source for the poor, and they could be satisfied as long as they caught it themselves.
