Medical staff are fighting covid-19 at the front line. They have insisted on sticking to their posts during this special period. They protect everything like heroes. Heroes also have troubles and challenges. They need social affirmation and social respect, but they also need practical help. The public only saw their struggle, but did not see the sadness behind them. I want to use this project to better understand the real situation of medical staff in this special period, analyze the problems and challenges they encounter, and explore different ways to help them.
