Dear Jack,
I'm Li Hua from Class One, Grade Three. Having learned that you are hoping to find a host family, I'm writing to recommend mine for the following reasons.

We are more than happy to introduce Chinese culture and some tasty food to you. Last but not least, my home is close to our school and a neighborhood center, which will be very convenient for you.

Yours,
Li Hua
