Dear Anna,
How glad I am to hear from you and to know that you are getting on well with your Chinese study at Beijing University.
To learn a foreign language, one should not only study the language itself, but also study the everyday life of the native speakers of the language. You`ve been in China for only half a year. I don`t think you have known much about our life at home. Why not come to my place and spend the Spring Festival with my family?
My parents and I are looking forward to seeing you. We`ll surely meet you at the station.
Best wishes!
Yours,
Li Hong
