Now,I know a lot about public signs.This is "No smoking",It means we shouldn”t smoke.This is "No littering",It means we shouldn”t litter.This is "No Parking",It means we shouldn”t park.This is "No eating or drinking" ,It means we shouldn”t eat or drink.This is "Do not touch", It means we shouldn”t touch.This is "Danger",It means we must stay away.This is "Keep off the grass",It means we shouldn”t walk on the grass.This is "Be quite",It means we shouldn”t make noise here^^
That”s all.Thank you!
