Hi thelmaresmi. There are no relative pronouns in Mandarin Chinese. The Mandarin Chinese has three kinds of pronouns: 1.personal pronoun (人稱代詞) 2.interrogative pronoun (疑問代詞) 3.demonstrative pronoun (指示代詞) Not all relative clauses contain relative pronouns. Some languages, such as Mandarin Chinese, do not have relative pronouns at all, and form relative clauses (or their equivalents) by different methods – these are described in detail in the article on relative clauses. (from Wikipedia) When translate a sentence to Chinese, in most cases,you can use ' relative clause + 的 + noun' to express your idea. For example: This is the house that Jack built. 這是Jack建的房子。 "This is the house" --> "這是房子" "that Jack built" --> "Jack建的"

who, whom, which, of which, whose 谁，谁，哪一个，的哪一个，谁的……

who, whom, which, of which, whose, etc means谁，谁，哪一个，xx的，谁的，例如。
