what's the difference of 她，他，它？

她：一般专指女性，有时用来比喻一些带有感情的事物。除此之外，抒发感情时，我们会把祖国，故乡，城市，学校等敬重和很有感情的事物比作母亲。例如：我在祖国母亲的怀抱里长大，不论走多远，我都深深眷恋着她。这里将祖国比做母亲，用“她”代指，表达自己对祖国的爱欲眷恋。

他：一般用来代表男性，也可泛指所有的人，包括男女老幼。因此“他”指代的人有男有女，当有可能是男也有可能是女时，即性别不确定是一律用“他”，“他们”就可以。例如：同学们都去植树了，他们一共要植300棵树。此处“他们”指代“同学们”，因为同学们里可能有男有女。

它：“它”指的是一切除了人以外的物体或者事物
“它”，用来泛指不是人的一切，如动物，食物、植物，工具。例如：学习过程中电脑是一种必不可少的学习工具·，要用它来查看资料。“

The pinyin for these three characters is the same: ta with the first tone. However, the characters mean differently even though they are all pronouns. Here, it's worthy of noting that these few pronouns are the only case that people can identify the person is female or male because Chinese does not really have gender differences, unlike Spanish or French.
More specifically,
他-he/him (when you want to use this pronoun with a male person)
她-she/her( when you want to use this pronoun with a female person)
它-most of the time, it's like" it" in English, when you want to use pronoun to describe someone or something is hard to identify the gender or you not sure the gender. 它 also can be used when to describe unlived things, in other words, objects who don't have lifes.
Hope this helps.

In Mandarin Chinese, 他 (tā), 她 (tā), and 它 (tā) are all third-person singular pronouns, they have the same pronunciation but they are used to refer to different person or things in differnt contexts. Simply speaking,
他 (tā) =he or him 她 (tā)=she or her 它 (tā)= it

They can be used as both the subject and object of a sentence.

In Mandarin Chinese, 他 (tā), 她 (tā), and 它 (tā) all mean "it" or "he/she" but they are used in different contexts.
他 (tā) is used to refer to a male third-person pronoun, similar to "he" in English.
她 (tā) is used to refer to a female third-person pronoun, similar to "she" in English.
它 (tā) is used to refer to a non-human object or an animal, similar to "it" in English.

It's important to note that while 他 and 她 are gender-specific, 它 is not and can be used to refer to both male and female non-human entities, as well as inanimate objects.

她 refers to females, 他 refers to males, and 它 refers to animals and objects with no life.

她 = She
他 = He
它 = It
