有 yǒu: showing existence

有 yǒu iterally means to have, which can show the possession. For example, 他有很多小狗。(He has lots of dogs.) It can be also used to indicate the existence of someone or something in particular place. For example, 

• 学校里有书店。Xuéxiào lǐ yǒu shūdiàn. There is a bookstore at school.
  
• 杯子里有什么？ Bēizi lǐ yǒu shénme? What is (there) in the cup?
• 房间里没有人 。Fángjiān lǐ méiyǒu rén. No one in the room.

In these sentences, verb 有 (yǒu), which means "to have", can also be used to express existence. This is similar to saying "there is" or "there are" in English, and is sometimes expressed in other ways as well. The structure is Place + 有 + Object.
