True. In Chinese, pronouns are generally not marked for case like in some other languages (such as English). There is one set of pronouns that serves as both subject and object, and possessive forms are created by adding a possessive marker. For example:
- I (subject) - 我 (wǒ)
- me (object) - 我 (wǒ)
- my (possessive) - 我的 (wǒ de)
So in Chinese, the same pronoun can be used for multiple grammatical roles, with a different form for possession.
