The English translations on some signs in China don't always make a lot of sense because of grammar, syntax, idiom and spelling issues, etc. So they can be rather amusing, like this one that is near the Great Wall.
The message reads:
"May we remind you: Please be self-restraint and be a good tourist to mold a well-mannered imagination."
You can guess they're just telling you to act nice.
