Through a deep research of the Grammatical fetures and Syntax function of the Classical Chinese Pronoun—“Zi”, while it is in the time known as separatedly-used, this paper finds that the Classical “Zi” owns three functions known as Correlative, Emphasis and Analogy. Sincet he Antecedents of “Zi” is able to be discovered in its jurisdictional term regions, it proves that “Zi” accept local binding, which follows the First principle of Binding theory. Since the Classical “Zi” is more similar to the Correlatives in Western languages including the English language, it can be categorized as reflexive pronoun among all Correlatives. Where ever the position of “Zi” in the terms, it is just a regional reflexive pronoun, and can only find its Antecedents in its jurisdictional regions which bound to the Binding theory of Chomsky. Therefore, “Zi” is not the factor which explains the reason why “Ziji” is able to accept Long-distance binding.
