今日立冬
立冬，是二十四节气之中第十九个节气，也是冬季的起始。《月令七十二候集解》有云：“立，建始也；冬，终也，万物收藏也。”立冬，意味着生气开始闭蓄，万物进入休养状态。其气候也由秋季少雨干燥向阴雨寒冻的冬季气候过渡。
Lidong(beginning of winter) is the 19th of the 24 solar terms and marks the beginning of winter. According to the ancient classic, "Li means to establish; Dong means the end. Everything begins to store up." Lidong signifies the time when vitality starts to retreat, and all living things enter a dormant state.
立冬在古代社会也是“四时八节”之一，是个非常重要的节日，在中国部分地区有祭祖、饮宴等习俗。农谚有云：立冬之日起大雾，冬水田里点萝卜。民谚又说：立冬补冬，补嘴空。作为寒冬的第一个节气，自然有其农事意义和养生价值。
In ancient society, Lidong was one of the "Four Seasons and Eight Festivals," making it a very important day. In certain regions of China, there are customs such as ancestor worship and feasting. There are agricultural proverbs that say: "If heavy fog begins on Lidong, it will be a good time for winter crops," and "Lidong to the time to prepare for winter, fill the empty mouth," suggesting that this is a time for replenishing one’s energy for the cold winter months.
一候水始冰，指天地愈渐寒冷，水面便开始逐渐凝结，河面变得越来越纯净安宁；二候地始冻，随着冷风侵袭，早晚温差变大，薄霜初现，静悄悄躺在湿润的土地上；三候雉入大水为蜃，形容此时野鸡蛰伏了，而蛤类则大量繁殖，这源于古人的幻想。
The first period: Water begins to freeze. The second period: A light frost begins to appear quietly on the moist ground.The third period: The pheasants disappear and shellfish, such as clams, breed in large numbers.
