I was searching just now, and I probably found the identification method of 10 days.

I have accumulated a little.

1, what we want to see is the bottle cap. On the side of the bottle cap, there is a small square that presses the vertical stripes of the bottle cap. At present, there are only three lines and two lines.

Master Kong: If the cube presses three lines, it means "another bottle". If you press two lines, it means "thank you for your patronage".

Unity 1: If the small square presses two lines, it is "another bottle". If it presses three lines, "Thank you for tasting"

2. The color of stockings is almost colorless, and stockings or pantyhose can be worn on your hands. Then you can gently touch the cover with the front end of the sock, only once. According to the first feeling, if it's a little bumpy, it means "another bottle", and if it goes well, it means "thank you for your patronage" (Master Kong only).

3. There are two conspicuous places on the bottom of the bottle with fonts, one is "K" and the other is the number 1 to 10. The result I got was a bottle with K 9 written on it, which had a higher chance of winning the prize.

You can buy a bottle of master kong tea, such as honey tea, unscrew the lid ... don't unscrew it ... shine a flashlight on the lid ... there is a small gap on the lid every once in a while. You can see the words inside through that small gap. If you can't see it, you can pick it up with something sharp and try it with a flashlight.
