The method of reading the year of the clothes on the card is as follows:

1. Direct reading method: Some clothes will have a clear year, month and day marked on the tag, which can be read directly.

2. Code notation: In the code notation, the year, month and day will be represented by three or four digits on the tag. For example, YY/MM/DD is used to represent the year, month and day. It means the production date.

3. Batch information: Observe the item number of the product. The item number of some brands will contain production date or batch information. For example, if the product number of a certain brand is ABC-2019-001, then this piece of clothing was produced in 2019.

4. Brand marking: Some brands will mark the year and season of production on the hangtag. For example, a brand's hangtag reads "2019 Spring and Summer Style", which means that this piece of clothing is a new style launched in the spring and summer of 2019.
