Subject pronouns in a sentence refer to the speaker, the listener, or a person or thing mentioned. In Chinese, subject pronouns are commonly used to clarify who performs the action. Pronouns are usually placed before the verb, serving as the subject of the sentence. Choosing the correct pronoun can make the meaning of the sentence clear.

Chinese subject pronouns are divided into first person, second person, and third person. First person is the speaker, second person is the listener, third person is other people or things mentioned. Each category has its corresponding basic form. When choosing a person, base it on the addressee and the referent.

Chinese third-person pronouns have gender distinction; in spoken form the pronunciation is the same, but the written form differs. 'He' usually refers to males or generic people, while 'She' typically refers to females. In written language, choose the correct character based on the referent.

When referring to objects with Chinese third person, '它' is often used. 'It' is used for animals, items, or abstract things, and is not used to refer to people. Choosing 'It' helps avoid confusion between people and objects.

Chinese subject pronouns add '们' to indicate plural, referring to more than one subject. 'We' is first-person plural, 'you all' is second-person plural, 'they','they','they' are third-person plural. Plural is often used to emphasize a group of people or things as the subject.

Subject pronouns are usually placed at the beginning of the sentence, followed by a verb or linking verb. This position indicates who is the actor or the one bearing the state. In declarative sentences, the pronoun plus verb is the most basic structure. In short Chinese sentences, a pronoun can stand alone as the subject.

In spoken Chinese, if the subject is known, the subject pronoun can be omitted. Omission usually occurs in dialogue where both sides clearly indicate who is referred to. Even after omission, the sentence can still convey complete meaning, but in writing the subject is generally retained. Whether to omit depends on contextual clarity.

In formal or polite situations, Chinese often use '您' instead of '你'. '您' is a respectful form addressing the listener, common in service contexts, with elders, or formal communication. '您' and '你' both act as the subject, but '您' is more respectful. Choosing '您' demonstrates politeness.

"I" refers to the speaker, "you" refers to the listener, and "he/she/it" refers to a third party or things. Adding "们" forms a plural, indicating multiple people or things. In third-person writing, distinguish "he" and "she"; refer to objects with "it". Correct references ensure the meaning of the sentence is clear.
