If you encounter words or patterns that you don't recognize, you can refer to the following methods to identify them: 1. Observe the shape and structure of the font and try to guess its letter or pattern combination. For example, some letters or patterns may have similar shapes and structures, so they can be used to guess the words or patterns on the plate. 2. Use image search engines or image recognition software. These tools could help search and identify patterns or words on the plate. 3 Ask your family or friends if they recognize the words or pictures. Sometimes people might find information about themselves, such as the names of family members or places they had been to. If you're not sure about the meaning of these words or patterns, you can try asking your local museum or cultural institution to see if anyone can explain their meaning. No matter which method you choose, you must be cautious and curious. Don't abuse your curiosity to invade other people's privacy or property rights.
