How to tell whether Tsingtao beer is produced in Jinan or Qingdao? The packaging is the same. One says Qingdao, the place of origin, and what's even more amazing is that the other says.

Tsingtao Brewery has factories in many cities all over the country. The main products are classic, pure packaging and LOGO, the only difference is the factory code. You can look at the box or bottle cap. There are two lines of code on the bottle cap. The first line is the production date, such as 20 13 102 1. The first two digits in the second line are factory codes, for example, 0 1, 02 and 03 represent Qingdao No.1 Factory, No.2 Factory and No.3 Factory respectively, 24 represents Anshan Factory and 60 represents Yantai Factory. 2 represents the second production line, and the remaining codes represent the delivery time of wine, for example, 12: 45, which means 12:45. I hope the above answers are helpful to you.
