Look at the batch number at the bottom of tf lipstick.

1. First of all, the bottom batch number of tf lipstick consists of three digits, and the first digit can generally be ignored, because it is the production batch number, which has nothing to do with the production date and has no special meaning, and can be viewed directly from the second digit.

2. The second digit is generally the number 1-9 and the letter A/B/C * * 12, corresponding to 1-65438+ February respectively, where A is 10 and B is1/kloc-0.

3. The third digit is also a number, ranging from 0-9 to * * * 10. For example, 0 means 2020, 1 means 202 1, 8 means 20 18, 9 means 20 19 and so on. Some people may say that 9 can't mean 2009, obviously.
