In order to train the younger generation of medical workers, I would like to be a ladder. In discipline construction, we should actively promote the integration of cardiology and surgery, give consideration to the construction of pediatrics, create advanced scientific models, better serve patients, and be more conducive to discipline development. It is unique in the cardiovascular field in China.
