In high-pollution days with PM2.5 greater than 75 μg/m3, the reductions of PM2.5 in Case 3 were 7.78, 9.51, 11.38, 13.42, 13.64, 14.15, 14.42, 16.95 and 22.08 μg/m3 in Shanghai, Jinan, Shijiazhuang, Beijing, Taiyuan, Xi'an, Tianjin, Zhengzhou and Wuhan, respectively. This study highlights that large emissions reduction in transportation and slight reduction in industrial would not help avoid severe air pollution in China, especially when meteorology is unfavorable. In order to investigate the effect of reduced anthropogenic activities on air pollution, three simulation scenarios were performed and compared (Table 1) the Case 1, Case 2 had a decrease of 40% and 20% in transportation and industry emission, respectively.	./cache/cord-313420-ubm8j1xe.txt	./txt/cord-313420-ubm8j1xe.txt
