     My name is Chen Lan. My home is in Gulangyu. Where is Gulangyu, do you know? It is in Xiamen.

It is near the sea (海). Gulangyu is a small place, but it is very nice and clean. There are no cars, no buses

and no bikes. People only walk. So it is very quiet.Our house is in the middle of Gulangyu. Behind our house

there is a big old tree. My grandfather tells me the tree is very old. There are many birds in the tree. We call

it "bird tree".

      Our house is near the sea. The sea is big and blue. There are a lot of fish in the sea. After school, I go

there and catch fish with my friends. It is very interesting. I like eating and catching fish.
