灿烂阳光祝全体员工冬至快乐！冬至是中国的传统节日，兼具自然与人文两大内涵。它是二十四节气之一，被视为冬季的大节日。古代民间有'冬至大如年'的讲法，所以古人称冬至为'亚岁'。这天北半球的太阳高度最小，太阳光直射南回归线，使得冬至是北半球最为倾斜的日子。在此期间，人们会祭祖、吃冬至团和其他民间习俗。 Winter Solstice is a traditional Chinese festival that combines natural and humanistic elements. It's one of the 24 solar terms and is considered the biggest festival of winter. In ancient times, people had 'winter solstice is big like a year' sayings, so they called winter solstice 'Astronomical Era'. On this day, the sun's height in the northern hemisphere is at its minimum, and the sun's rays are most direct towards the southern direction. During this period, people will perform ancestor worship, eat winter solstice buns, and engage in other traditional customs.
