Dear Mr and Mrs Johnson，
I am Wu Gang.I have been back home inChina. I am too eager to write a letter to you and your family the momentmy feet hit the land of China. In the pastfour years，you have treated me like yourown child，caring about my study and life. WheneverI was in trouble，you werealways giving me a hand.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 andindependenceliving ability.
Now I am making everyeffort to apply for a job.Welcome to China.If you come，I can act as a guide and youwill enjoy yourselves.
Best wishes!
Yours，
Wu Gang
