The traditional Chinese lunar calendar divides the year into 24 solar terms. Minor Cold (Chinese: 小寒), the 23rd solar term, falls on Jan. 6 this year.

During Minor Cold, most areas in China have entered the bitter cold stage of winter. The ground and rivers are frozen. The cold air from the north moves southward continuously.

Although "Minor Cold" means less cold than the following solar term, "Major Cold", there is an old saying in China that goes, "The days of the Sanjiu period are the coldest days." "Sanjiu period" refers to the third nine-day period (the 19th-27th days) after the day of the Winter Solstice, which is in Minor Cold. Minor Cold is usually the coldest period of winter. It is essential to keep warm during this period.

During Minor Cold, people start stocking New Year goods, which include Spring Festival couplets, New Year pictures, paper-cuts for window decoration, firecrackers, incense and lanterns. To prevent coldness, eating food that can provide heat and energy to the human body is better. Mutton hot pot, chestnuts and baked sweet potato are three recommended foods for Minor Cold.
