"I want to work full-time in China, honey." An overseas call awakened the wife from sound sleep. "Why?" asked the wife with surprise, in a drowsy（昏昏欲睡的）voice, from the other side of the ocean.
In the United States, he had a great future ahead. At the age of 36, he became the youngest professor in the history of the Department of Molecular Biology at Princeton University, for his academic achievements. At 40, he became a tenured（终身的）chair professor at Princeton.
When everything seemed perfect and admirable to others, he firmly decided to say goodbye to Princeton University, to an affluent life in the United States, and return to China.
The news spread explosively. Many expressed confusion, many persuaded him, many made fun of him, and still many waited to have a good laugh at him.
He said patriotism is the plainest feeling of a person. Who doesn't love his motherland, after all? In his heart, the American dream is already something past; the Chinese dream is rising.
After returning to China, he devoted all his energy, worked like crazy, and determined to do something big. He formed a life science research team. Every day, he works 12 to 16 hours at his laboratory.
He is Shi Yigong, nicknamed "Da Niu"（someone with extraordinary achievements）by Tsinghua students. His given name, Yigong, comes from an idiom that means "devoted to public interest whole-heartedly". "So far as I' m concerned, awards are of no special meaning." Shi says calmly.
In his 18 years of study in the United States, he never forgot his Chinese dream. In the next 18 years, the Chinese dream will be more beautiful and greater by the efforts of Shi Yigong and the likes of him.
