Here are some examples:
* 我的爱好是阅读。 (Wǒ de àihào shì yuèdú.) - My hobby is reading.
* 你喜欢什么爱好? (Nǐ xǐhuan shénme àihào?) - What are your hobbies?
It's important to note that while "aihao" can be translated as "hobby", it often has a broader meaning than just "hobby". It encompasses any activity someone finds enjoyable and enjoys doing regularly, not just activities done in their free time.
