Dr. zhongnan has a strong personal ability. The reason why going to Tibet can save more people is because there are still many diseases in Tibet that cannot be solved. Dr Nan Zhou can use his professional knowledge to solve some unsolvable problems in Tibet. And if he stays in Beijing, there are many doctors who are more capable than him. Although Beijing has a large population, the number of people saved by doctors in Nan Zhou is still relatively small. Moreover, Tibet is relatively remote, and many poor people are reluctant to go to Tibet to help. This has also led to poor medical technology and fewer doctors in Tibet.
Tibet itself is located in the plateau, and its harsh climate is harmful to people's health and prone to illness. Dr Nan Zhou saw this situation when he visited Tibet before, so he put forward the idea that more people can be saved in Tibet. Moreover, there are few doctors in poverty-stricken areas in Tibet, and their ability is not very strong. So some people are seriously ill and are likely to die. When Dr. Nan Zhou went, he came to Tibet like an angel, which brought hope to some seriously ill people.
Dr. Nan Zhou has been breaking through some intractable diseases in Tibet since he entered Tibet, and now he has achieved some good results, which is also good news for people in Xizang. Therefore, Dr. Nan Zhou certainly saved more people in Tibet than he did in Beijing. I believe that after the incident of Dr. Nan Zhou, more and more people will go to Tibet to help Tibet become better.
