February 15, 2013 is American student David's 25th birthday. He secretly made a wish that hope his hospital practice can be smoothly. All of his families associated with the doctor in America. His parent are always concerned about his study.

David said, “I come to China is to reduce the burden of my family. Because of the children in the house are all studying medical science. The cost is too big.” David said that studying medical science in America needs five hundred thousand to seven hundred thousand dollars one year.

However David found gradually that studying medicine is not simple as he thought after he came to China. He said, “I want to study two books because my goal is going back to be a doctor. One is Chinese medical college teaching materials and other is practitioners of textbooks in the United States.”
