You have just gotten off a flight from Shanghai to New York. Dragging your tired body, you excitedly open your cell phone to reply to your family that you have landed safely. Along with a dozen hours of unread messages, you see a report about Covid-19. That was the same day that you landed in New York and an outbreak of unprecedented proportions broke out in China.

Covid-19 spread so quickly that the central government then made the decision to seal off Wuhan. More than 10 million people were forced to stay in Wuhan, and no one was allowed to enter or leave the city without special circumstances. And you, who had just landed in New York, were very lucky to escape for the time being.

Covid-19 dominated the daily headlines of the world's news media as the number of infected people in China spiked and the out-of-control movement of people spread around the world. With strict and decisive protest measures by the Chinese central government, the day and night efforts of countless medical staff and volunteers, and the highest level of cooperation and support from all Chinese citizens, the outbreak in China gradually improved, and after three months the number of infections was zero. However, the complex political, economic, and social factors around the world did not allow for a very good control. And you, as an ordinary international student, are also involved in this huge catastrophe.
