What I can learn from Tu Youyou
It is known to all that Tu Youyou is the first Chinese woman scientist to win a Nobel Prize. Drugs based on her research have led to the survival and improved health of millions of people across the world. There are many things I can learn from such a great scientist. However, what strikes me most is her attitude towards work and her devotion to the traditional Chinese medicine, which contributes to her discovery. It has proven to us that an old idea might lead to a new discovery. It is true that we have a lot more to learn from historical methods and practices. The traditional Chinese medicine treasure house is really worth exploring.
