Parts of east China's Shandong Province and the central province of Henan will also be hit by smog during the period, the Environmental Protection ministry said, citing a forecast by the China National Environmental Monitoring Center (CNEMC).
Yesterday, air pollution affected 100 of 338 cities monitored across the country. Northwest China's Xinjiang Uygur Autonomous Region and east China's Anhui Province suffered the most.
Three cities in the Beijing-Tianjin-Hebei region -- Beijing, Shijiazhuang and Hengshui -- were experiencing moderate air pollution while the air in the other 10 cities in the region was graded "good" or "light pollution".
Despite Beijing's attempts to limit air pollution, the capital saw only 186 days with air quality that met the national standard in 2015.
