Macau is a very small place that is made up of two main parts: Macau Peninsula and Taipa Island. It's located in southeast China and is close to Hong Kong. Macau has a lot of tall buildings and cool sights to see.
But what's really interesting about Macau is its geography. Macau is surrounded by water on three sides, which means it's like an island but it's connected to China. The water is called the Pearl River delta and it's a really important place for shipping and fishing.
Macau is also really hilly. That means there are lots of little mountains and hills everywhere, which makes it really pretty to look at. But it also means that the roads and buildings are built in a way that's different than some other places. There are lots of steep, winding streets that make it hard for cars to get around. But people in Macau love to walk around and explore their city, so they don't mind too much.
There are also a few smaller islands around Macau, like Coloane and Cotai, which are also really pretty. They have beaches and nature spots that people like to visit.
Overall, Macau's geography is really cool because it's both an island and connected to China, it's surrounded by water and hills, and it has some smaller islands nearby.
