### 冬至的由来（中文）
冬至的由来与中国古代天文学、阴阳五行学说和农耕文化密切相关。以下是其由来解释：
1. **天文学解释**：古代人们认为，冬至是全年中白天最短、夜晚最长的一天。这一天，太阳直射点达到南回归线，之后太阳会逐渐向北移动，白昼逐渐变长。
2. **阴阳五行学说**：根据阴阳五行学说，冬至这天阴气达到极致，阳气开始复苏。阴气盛极必衰，阳气将逐渐上升，万物将开始复苏。
3. **农耕文化**：冬至也是中国古代农耕社会中的一个重要节气。因为冬至之后，天气渐冷，农事活动逐渐减少，人们开始为过冬做好准备。
### 冬至的由来（英文）
The origin of the Winter Solstice is closely related to ancient Chinese astronomy, the theory of Yin and Yang, and agricultural culture. Here is the explanation:
1. **Astronomy**：Ancient Chinese people believed that the Winter Solstice was the day with the shortest daylight and the longest night of the year. On this day, the sun's direct ray reaches the southernmost latitude, the Tropic of Capricorn, and then begins to move northward, gradually increasing the length of daylight.
2. **Yin and Yang Theory**：According to the theory of Yin and Yang, the Winter Solstice is the day when Yin energy reaches its peak and Yang energy begins to rise. As Yin energy is at its most potent, it will inevitably decline, while Yang energy will gradually rise, heralding the revival of all things.
3. **Agricultural Culture**：The Winter Solstice is also an important solar term in the traditional Chinese agricultural society. After the Winter Solstice, as the weather becomes colder, agricultural activities gradually decrease, and people start to prepare for the winter ahead.
