The main routine is to switch packages. If the boss selling fish is black-hearted, he will replace the fresh fish bought by consumers with the prepared dead fish when consumers are not paying attention, and let these bosses sell those dead fish. This is also one of the most important methods. Although many consumers have been aware of this kind of thing and have been paying attention to this phenomenon, ordinary people can't tell the difference between fresh fish and fresh fish. Even if consumers do this, the "black-hearted boss" may still say that the fish died while packing. The second routine is to sell it to some meat processing shops. Of course, this is just the leftover fish that you didn't buy under the 1 routine. This kind of fish is even more stale. Maybe you can see it's different from the outside. It is more likely that fish has a taste, so it will be sold to these meat processing shops, which will not be selective. He can buy it as long as the price is cheap enough. Finally, various pigments and monosodium glutamate are added to improve the taste of the fish, so that the fishy smell of the dead fish can be masked and sold to consumers again. So if you encounter the kind of fish processed products that are particularly cheap, try not to choose to buy them.

The last one is to sell the remaining fish to a processing factory. The technology of the processing factory is much higher than that of the braised pork shop. They can process any fish, let alone whether it is fresh. Think about it carefully, a fresh fish sold in the market costs at least tens of yuan, but you can't reach the price of fresh fish if you buy a catty of processed fish balls. Why? Even the cost is too low to process, it must be because of the difference in fish. The fish in the fish balls is definitely incomparable with the fresh fish.

Advise consumers not to covet petty advantages, or go to a formal place to buy.
