China's central and southern regions are set to be hit by sleet and strong winds this week, after dense fog disrupted travel over the weekend as millions returned to work after the Chinese New Year holiday. Starting yesterday, northern regions including part of Inner Mongolia will see heavy snow, while sleet and rain will cover the majority of central and southern regions, the China Meteorological Observatory said.
