However，depending on the better control of the epidemic in China，both the film screening and production have been gradually restored. This article uses a combination of industrial analysis and artistic analysis to sort out the industry overview and important industry phenomena in 2020. This article believes that in terms of industrial policy，fighting the epidemic has become the most important theme of China’s film industry in 2020.
