However, to say "My" in Mandarin, you need to use a possessive pronoun, which changes depending on the object you are referring to. Here are some examples:
* 我的 (wǒ de) - My (for things you own, like "my book")
* 我的 (wǒ de) - My (for people you are related to, like "my brother")
* 我的 (wǒ de) - My (for body parts, like "my hand")
* 我的 (wǒ de) - My (for emotions or feelings, like "my happiness")
So, to say "My" in Mandarin, you need to add "的 (de)" after "我 (wǒ)" and then specify what you are referring to.
For example:
* 我的书 (wǒ de shū) - My book
* 我的哥哥 (wǒ de gēgē) - My brother
* 我的手 (wǒ de shǒu) - My hand
* 我的快乐 (wǒ de kuàilè) - My happiness
