Hello, Jenny!

Today is the Mid-Autumn Festival. We will watch the moon tonight, and look for Chang’e and Wu Gang. We usually eat mooncakes. They are round, like the moon. National Day is also in autumn, on October 1^st. My mother and father are usually free for seven days! We will do many things together. I like going to the National Day celebration. But the best thing in autumn is my birthday. It’s in October. I will be fifteen years old. Goodbye.

Yours,

Li Ming

Dear Li Ming,

Thank you for your e-mail! I love autumn too. In Canada, we have an autumn holiday called Thanksgiving Day. Family members always celebrate it together. I will go to my grandmother and grandfather’s house. My uncles, aunts and their children will be there too. Canadian Thanksgiving Day is in early October. In the USA, they celebrate Thanksgiving Day in late November. Have a good time on your birthday, Li Ming! On my birthday, I have a cake with candles. Everyone sings the song “Happy birthday”. Then I blow out the candles! Will you have a cake for your birthday?

Your friend,

Jenny
