This is a funny sign. But if you take it seriously, it would be very dangerous. Can you imagine? You take your child and fall into water carefully. Or do they mean “walk” into the water carefully? Or is there such a thing? Or many, “swim” into the water carefully, but are you supposed to take your child? Maybe, maybe not. Whatever, just be careful and take your child, he might fall into the water and drown. Looking at the water color, you would not like it.
