The traditional Chinese lunar calendar divides the year into 24 solar terms. Xiaohan, or Minor Cold, is the 23rd solar term, which falls on Jan 6 this year.

During Minor Cold, most areas in China have entered the bitter cold stage of winter. Many places in China have been covered with ice and snow.
