How to identify Chinese cigarettes with the prefix 3

The prefix "3" refers to the production specifications of cigarettes. The specific steps for identification are as follows:

1. First distinguish between hard boxes and soft boxes, because Chinese cigarettes in hard boxes do not have 1.2.3 By prefix.

2. Use your naked eyes to look carefully at the upper left corner of the side with the Tiananmen image and look at the last three digits in the second row of numbers.

3. Use ultraviolet light or light to clearly see the second row of numbers, and you will see the words starting with 3.2.1. The last three numbers in the second row represent the prefixes. For example, 327 is the prefix "3", 229 is the prefix "2", and 118 is the prefix "1".

4. Open the cigarette in the packet, and when you smoke it, you will see an obvious small red number on the ignition end.
