| Abstract: | When Xing Zuzhong, a medical worker in Hunan Province, central China, went to neighboring Hubei to help control the novel coronavirus epidemic in early 2020, he had no idea that he would become a statistical milestone. On December 22, 2020, after the situation was well under control, Xing received an unexpected gift from his co-workers in Hubei. The package also happened to be the 80 billionth package delivered by the country's courier sector in 2020, according to data from the State Post Bureau (SPB). |
