When talking about the experience of studying in Harvard University in the United States, Professor Song's deepest feeling is that in the United States, scholars' research attitude is more pragmatic, not formal, and always focuses on research results. Professor Song's laboratory is CBR Institute of Biotechnology, Harvard Medical School, USA. Supported by 1 1 National Natural Fund, there are various research institutes around. Many top experts work here, including 1996 Nobel Prize winner philip sharpe, who is also our close neighbor. This facilitates the research work and makes it easy to find collaborators. Song's enterprising personality is very suitable for the working atmosphere of American laboratories. Once, Song and his tutor argued whether the subcutaneous tissue of a mouse was a tumor or cartilage. In the face of a lot of evidence, his tutor finally admitted his mistake. Under this kind of equality and openness, real money is not easy to be buried, and only talented people can play it. These valuable experiences in studying abroad have greatly inspired Professor Song to carry out his own scientific research work after returning to China: he has always insisted on down-to-earth and sincere scientific research activities. Professor Song believes that China has better development opportunities and scientific research prospects, and has the most tacit cooperation partners, so he chose to return to China after studying in the United States, and under the drive of his heart, he is constantly moving towards new goals.

Compared with foreign concentrated scientific research, the multiple roles in China undoubtedly require Professor Song to invest more time and energy. In the hospital, Professor Song is the deputy director of the Second Affiliated Hospital of Sun Yat-sen University. He needs to wear a white coat and treat patients like ordinary doctors. When a graduate student visits Professor Song and wants to participate in the research in his laboratory, he will discuss professional problems with them in the aisle, in the small garden and in the elevator. In the laboratory, he will talk about his future work with his assistants and students easily. For the change of these roles, Song seems very calm: "In fact, my goal was set before or after going abroad, that is, to serve my compatriots with my own medical technology. No matter how I turn, it is a process, all for the original dream. "
