There are a lot of things in this world that do represent different kinds of things and those are the signs. Like the most common sign that everyone knows, which the hands are. The hands do a lot of signs, which do represent different kinds of things. Thumbs up is one of the common hand signs, which means ok, if the pointing finger and the middle finger pointing up it means peace. Sign is really important to inform people and to remind people on the thing that they commonly forget, or they use it to communicate with other.
