Chinese font design and English font design as well as graphic design are derived from the shape of the paper clip. There are four cards in a card set. The card sets and cards are fixed by a paper clip. The shape and significance of the paper clip symbolizes the itinerant exhibition, which, like a paper clip, has traveled nine cities over nine years.
