One of the twenty-four solar terms “Winter Solstice”

The winter solstice is a very important solar term in the Chinese lunar calendar. It is also a traditional festival of the Chinese nation. The winter solstice is commonly known as “winter festival”, “long solstice festival”, “ya Sui”, etc., as early as spring and autumn more than 2,500 years ago At that time, China has used Tugui to observe the sun and determined the winter solstice. It is the earliest one of the twenty-four solar terms to be drawn up. The time is between December 21st and 23rd of the solar calendar every year. This day is the northern hemisphere of the whole year. The day is the shortest day and the longest night; most parts of northern China still have the custom of eating dumplings and glutinous rice balls in the south.
