Barcode or barcode is a graphic identifier that arranges several black bars and blanks with different widths according to certain coding rules to represent a group of information. The bar code can tell you whether this thing is really imported.

Because the first few digits of the bar code indicate the origin of the product, milk powder and milk are the same. The first two digits of the bar code of Australian milk are 93, which is imported from Australia. You can write down the bar codes of common milk producing areas, and you can quickly identify them.

Milk also tightens the skin. If you get up in the morning and find that your eyelids are swollen, you can mix some milk with vinegar and boiling water, then gently press it on your eyelids for 3 to 5 minutes, and then apply it with a hot towel for a while, and your eyelids will swell up instantly. Others: first soak two cotton pads in frozen milk, then apply them on swollen eyelids for about 10 minutes, and then wash them with clear water.
