2. Early winter folklore: brewing yellow wine and swimming in winter. It is a traditional Shaoxing wine-making custom to start brewing yellow wine in beginning of winter that day. The low water cooling temperature in winter can effectively inhibit the growth of miscellaneous bacteria and make the wine form a good flavor in the process of low temperature and long-term fermentation. This is the most suitable season for wine fermentation. Therefore, Shaoxing people regard the next year's trip from beginning of winter to beginning of spring as the most suitable time to brew yellow rice wine, which is called "winter brewing" to pray for happiness.
On that day in Harbin and beginning of winter, the athletes of Heilongjiang Winter Swimming Association crossed the Songhua River to welcome the arrival of winter. In addition, winter swimmers spent the day in this way in Shangqiu, Henan, Yichun, Jiangxi and beginning of winter, Wuhan, Hubei.
