Dear Betty,
How are you? I know you want to learn about Chinese culture, so I'm writing to invite you to spend the Spring Festival with me.
The Spring Festival is the most important traditional festival in China. We will have a big dinner with my family. My mom will teach us how to make jiaozi, a kind of traditional Chinese food. I can also teach you to make paper-cuts, which are a symbol of Chinese culture.
If you are available, let's meet at the school gate at 9 a.m. next Sunday. Then we can go to my house together.
I truly hope you can come to my house and enjoy the festival with us. Looking forward to your reply.
Yours,
Li Hua
