Xi is pronounced SHEE....pronunciation, not gender.
Actually the Chinese don't use personal pronouns.
From Wikipedia: Chinese pronouns (Chinese: 代词; pinyin: dàicí) differ somewhat from pronouns in English and other Indo-European languages.
For instance, there is no differentiation in the spoken language between "he", "she" and "it" (though a written difference was introduced after contact with the West), and pronouns are not inflected to indicate whether they are the subject or object of a sentence.
Mandarin Chinese further lacks a distinction between the possessive adjective ("my") and possessive pronoun ("mine"); both are formed by appending the particle 的 de.
So WHO knows how they differentiate the genders. It's all Greek to me.
