In Chinese, the primary possessive particle is "的" (de). It is used to indicate possession or to form possessive constructions by linking a possessor (usually a noun) with the thing being possessed. Here are some examples of how "的" is used as a possessive particle:

1. 我的书 (wǒ de shū) - My book

   "我" (wǒ) means "I" or "me," and "书" (shū) means "book." "的" (de) is used to show that the book belongs to "我" (wǒ).

2. 他的家 (tā de jiā) - His house

   "他" (tā) means "he" or "him," and "家" (jiā) means "house." "的" (de) indicates that the house belongs to "他" (tā).

3. 她的手机 (tā de shǒujī) - Her cellphone

   "她" (tā) means "she" or "her," and "手机" (shǒujī) means "cellphone." "的" (de) signifies that the cellphone belongs to "她" (tā).

4. 我们的车 (wǒmen de chē) - Our car

   "我们" (wǒmen) means "we" or "us," and "车" (chē) means "car." "的" (de) is used to indicate that the car belongs to "我们" (wǒmen).

5. 你们的狗 (nǐmen de gǒu) - Your dog (referring to a group of people)

   "你们" (nǐmen) means "you" or "your" (plural), and "狗" (gǒu) means "dog." "的" (de) shows that the dog belongs to "你们" (nǐmen).

It's important to note that "的" is not only used for indicating possession but also plays a role in forming adjectives, relative clauses, and other grammatical constructs in Chinese. The specific meaning of "的" in a sentence depends on its context and usage within that sentence.
