I am an extremely ordinary grassroots internal medicine doctor. Whenever others call me "angel in white", I always feel ashamed. I am sure that I am really not an angel. I am at best a "soldier" wearing a white coat who has a certain respect for life. However, this soldier has also experienced abjection, deception, panic and despair - but fortunately, although there are many sick people in this world, there are also many good people. After so many thrills, everything returns to nature and beauty! Where dreams are, there is hope! Come on, Ollie! ! !
