Classification significance of serial number

Some people think that the word "serial number" comes from Japanese, and the pronunciation of Hiragana is "ばんごぅ", which means the number placed and can also be called a number. For example, the house number is the room number and the phone number is the phone number. However, "serial number" was also used in earlier documents in China, such as the military serial number in the Republic of China.

The classification of serial numbers is also to meet the arrangement of each group number. In fact, it is the "product number" set by the film manufacturer for the product. Generally speaking, every movie from Japan will have its own serial number, which is usually represented by English letters and numbers. This is commonly known as the serial number, and the serial number of each manufacturer is different.

Not only that, movies, magazines and so on. They are all numbered. Homework is no exception. Every book has a unique serial number. ? The location of the serial number is generally in the lower left corner of the cover (if not, look elsewhere). ? The arrangement is mostly a combination of English abbreviations and numbers. The letter part is related to the company name or series. It all makes sense.
