2016 The beauty of Chinese characters -〔Heart〕. The China exhibition. Chinese characters are ideographical in nature. These two series of posters are typeset by superimposing 525 characters containing either one of the two "xin" radicals (“xin” meaning "heart" in Chinese). Writing systems are like humans in that they interact closely with the heart at various levels of feelings, emotions, moods, character, aspirations, mental activity and living conditions. Although a common human experience, this form of expression is uniquely Chinese.
