Hi! Tom,
I'm glad to hear that you are interested in traditional Chinese festivals.
My favorite festival is the Mid-Autumn Festival. It usually comes in September or October. On that day, our family members usually get together and have a nice meal. After that, I always admire the moon and share mooncakes with my families. I love this festival because I like eating mooncakes. They are in the shape of a full moon. They carry people's wishes to the families they love and miss.
In short, the Mid-Autumn Festival is a day of pleasure and happiness. I hope that my letter will help you know more about Chinese festivals.
Yours,
Li Hua
