I was in China a few months ago as per the photo. There were some marvellous signs, especially in the hotels, which had creative translations into English. The intent was more or less clear, but the sentence structure was challenging sometimes.
Goodness knows what the reverse would be-I am sure that as Chinese tourism to the West increases similar challenges will arise!
This sign which clearly and most politely advises one should keep off the grass and does it in a delightful manner and brings a warm smile to boot.
