For example, there is no differentiation in the spoken language amongst "he", "she" and "it" (even though a written difference was launched following speak to with the West), and pronouns remain the same whether they are the matter or object of the sentence. Mandarin Chinese more lacks a distinction in between the possessive adjective ("my") and possessive pronoun ("mine"); both are formed by appending the particle “的” (de). 

There are just three basic pronouns in spoken Mandarin:

I, me-我 (wǒ)
You-你 (nǐ)
He, 他/她/它 (Him/She, Her/It-tā) 

Plurals
Plurals are formed by adding 'men' at the end of the pronoun:

We, Us - 我们 (wǒ men) 
You - 你们 (nǐ men) 
They, Them - 他们(tā men) 

When speaking to elders or someone in authority, it is more polite to address them formally with 您 (nín) instead of the less formal 你 (nǐ).

Reflexive Pronoun

Mandarin also has a reflexive pronoun "自己" (zì jǐ), used when both subject and object are the same. For example:
她中饭都是自己烧的 (Tā zhōngfàn shì zìjǐ shāo de)。
She cooked lunch herself.
我自己 (wǒ zì jǐ)。
I myself.
