英语以实物为准怎么说

In English, we say "a picture is worth a thousand words" to mean that a visual representation of something can convey a lot of information or meaning more effectively than words alone. This phrase is often used to emphasize the importance of seeing something for oneself, rather than relying on someone else's description or interpretation. For example, if someone is trying to describe a complicated process or concept, they might say "I'll draw a diagram to show you what I mean; a picture is worth a thousand words in this case."
