The aim of this paper is to present a new Chinese input method through Korean Alphabet in cyber space. In chapter two, I have examined previous proposals on Chinese notation through Korean. In chapter three, I proposed a new Chinese input method through Korean Alphabet which can be used in cyber space. This new method is made on the concept of Medial Language which is suggested in this paper. Medial Language is a language system which is used in cyber space. If it is used in off-line, it could be used as a kind of phonetic symbol.
