Spells of cold wind had iced up the 121-kilometer-long section of the Yellow River in Baotou City, north China's Inner Mongolia Autonomous Region, as of December 18, 12 days earlier than last year. 

Low water flow and water level this year accelerated the freezing of the river. According to local authorities, the river began freezing on December 4, and now the entire section is frozen.
