Kelong is like a big house that is built on stilts over the water in the sea or river. The stilts are like very long legs that help the house stand up in the water. People use kelong to catch fish and seafood because they can put nets and traps in the water directly under the house. There are some rooms in the kelong where people can sleep, cook, and eat. It's like having a house on the water, but instead of living there all the time, people use it just for fishing.
