There are "routines" in supermarkets, so you should remember these points when buying things.

Many people like to eat cooked food, and I am one of them. I like duck goods, including duck collarbone and duck wings. There are many kinds of cooked food, including chicken feet, elbows, sausages, roast chicken and fried chicken. Many people don't want to cook, so they buy cooked food for convenience, but they must pay attention when buying cooked food, because some unscrupulous merchants will cook expired food again.

2. Fruit in the supermarket

Fruits in supermarkets are not only sold in bulk, but also in boxes. Usually, many fruits are packed together in a box. You'd better not buy this kind of fruit, because most of the fruits are bad, so it's a pity to throw them away, so the rest are made into boxes.

3. Meat in the supermarket

There are scattered packages of meat in the supermarket, especially mutton or chicken wings. Many people like to eat barbecue or shabu shabu shabu. There are kebabs of mutton, chicken wings and packaged mutton rolls in the supermarket. It is best not to buy these ready-made meats when buying them, because we can't tell whether they are good or bad. It's best to buy a whole piece of meat and process it at home. Although it is troublesome, it is safe to eat.

4. Food on supermarket shelves

There is a lot of food on the shelves in the supermarket. When you take the food on the shelf, you must take the food at the back. The food in front is often close to the production date, because the merchants are also afraid that these leftovers will go bad, so they put them in a conspicuous place.
