Is the internship in Shanghai Changzheng Hospital very tiring?

Tired. Shanghai Changzheng Hospital needs 12 hours to study surgical practice with doctors every day, and after studying for a period of time, I need to do my own surgical practice and be a nurse, so it is tiring to practice in Shanghai Changzheng Hospital. Shanghai, referred to as Shen for short, is the largest economic center and an important international financial center city in China, and is one of the first coastal open cities.
