Signs_标志

Yesterday I went to the park to play. I see a lot of different signs, but I dont know what that means. Then, a mark I pointed to the electric box above asked "Dad, the logo in the hand drew a slash is what mean?" My father replied, "it means you cant touch the box." I pointed to a sign on the grass and asked, "what does it mean?" Dad told me, "it means you cant walk on the grass."

Just one day, I know a few signs, how interesting.
