How can the difference between real and fake crabs be the same?

Every year, we see a lot of counterfeit Yangcheng Lake hairy crabs, and there are many measures taken, such as anti-counterfeiting labels, anklets, QR codes, etc., which can be said to be all-inclusive. But it seems that it has not been used for a year. From September to October, "fake" crabs are still rampant. The reason is actually very simple. The crabs in Yangcheng Lake are also crabs, and there is no difference in quality, appearance and taste from crabs in other places. The only thing that can tell the difference is the QR code of the anklet, but these are the most convenient for counterfeiting.

I remember watching a variety show two years ago, where an old crab farmer from Yangcheng Lake was specially invited to teach everyone how to identify the hairy crabs in Yangcheng Lake. The old man first praised how delicious the crabs in Yangcheng Lake were, and then introduced several characteristics of crabs in Yangcheng Lake: "green back, white belly, golden claws, and yellow hair"?, which he said clearly. After that, it was not enough. The program team specially found real and fake Yangcheng Lake hairy crabs to ask the elderly to distinguish. Fortunately, the old man chose the fake one. The situation was extremely embarrassing.

Although I don’t like crabs, my family loves this bite, so I buy some every year. But I have never seen any difference between Yangcheng Lake crabs and other freshwater crabs. The only difference is that they are more expensive, one is worth ten. But when it comes to how delicious it is, I really don’t think so. Sometimes I wonder if what I bought is actually fake, but seeing that the store has been on the TV news, it shouldn’t be the case.

Later, a friend who really knew the industry told me that my feeling was correct. They were just the same crabs. It was a joke to say that the water in Yangcheng Lake was suitable for breeding hairy crabs. Can a species be different if the water is changed? It's pure deception. The real value of Yangcheng Lake hairy crabs is not the hairy crabs, but the three words "Yangcheng Lake". These three words are famous brands. With these three words, the crab is no longer a crab, it is a luxury product. It should be sold at a high price. Since the crabs taste the same anyway, is it necessary to distinguish the real ones from the fake ones in Yangcheng Lake?

Although I am not convinced by my friend’s final conclusion. If it is false, it is false. But since then, I have never bought hairy crabs from Yangcheng Lake. This kind of luxury product should not be consumed by ordinary people. As for distinguishing authenticity from fake, that is a matter for wealthy people who can afford it and has nothing to do with me.
