Dear Mr and Mrs Johnson，
I am Wu Gang.I have been backhome inChina.Iam too eager to write a letter to you and your family the moment my feet hitthe land of China. In the past four years，you have treated me like yourown child，caring about my study and life. Whenever I was in trouble，you were always giving me ahand.Whenever I made progress，you were always sharing with me my joy.I am so grateful.Thank youvery much.
Over the four years，I have been well aware of thedifferences of family education between the two countries.For example，in China，our parents tend to doeverything for their children.In the USA，children are encouraged to develop working attitude andindependence?living ability.
Now I am making every effort to apply for ajob.Welcome to China.If you come，I can act as a guide and you will enjoy yourselves.
Best wishes!
Yours，
