There is an old saying in China that goes, "The days of the Sanjiu period are the coldest days. ""Sanjiu period", which is in Minor Cold, refers to the third nineday period (the 19th to the 27th day) after the day of the Winter Solstice(冬至). There are many different customs related to Minor Cold in China.
Eating hotpot
During Minor Cold people should eat some hot food to benefit the body and defend against the cold weather. Winter is the best time to have hotpot and braised mutton with soy sauce. But it is important to notice that too much spicy food may cause health problems.
Eating huangyacai
In Tianjin, there is a custom to have huangyacai, a kind of Chinese cabbage, during Minor Cold. There are large amounts of vitamins A and B in huangyacai. As huangyacai is fresh and tender, it is fit for frying, roasting and braising.
Eating glutinous rice(糯米饭)
According to tradition, the Cantonese eat glutinous rice in the morning during Minor Cold. Cantonese people add some fried preserved(腌制的) pork, sausage and peanuts and mix them into the rice.
Eating vegetable rice
In ancient times, people in Nanjing took Minor Cold quite seriously, but as time went by, the celebration of Minor Cold gradually disappeared. However, the custom of eating vegetable rice is still followed today. The rice is steamed and is unspeakably delicious. Among the ingredients(原 料), aijiaohuang (a kind of green vegetable), sausage and salted duck are the specialties in Nanjing.
