Hello, Chenjie!
It's autumn in October in Canada. Autumn is my favourite season. It's warm in the day and cool at night. You can see red leaves everywhere. The colour is very beautiful. Many people visit (游览) Canada in autumn because they like the red leaves and the weather. When you come here, you can pick apples with me on my uncle's farm. That's fun! Do you like autumn? What do you often do in your city in autumn? Please tell me.
Best wishes,
Linda.
