@@richardzhao792 sure that's true. The knowledge that he acquired in the US is invaluable to his later contribution to China. But I think as compared to his knowledge, his spirit that motivated him to return to the impoverished China only 5 days after his degree got conferred is more admirable. More than his knowledge in nuclear physics. Sorry that I cannot type Chinese with this computer.
I would say thank you for the great and selfless contribution that Dr Roy Vagelos have done to combat the HBV in China and all over the world. Happy birthday Dr Roy Vagelos!
