The Summer Solstice, one of the twenty-four solar terms, marks a crucial juncture when the sun's direct rays reach their northernmost point of the year, signifying the longest daylight hours in the Northern Hemisphere. On this day, the sun almost directly strikes the Tropic of Cancer, making the sun's altitude the highest of the year in areas north of the Tropic of Cancer.
The Summer Solstice is not just a solar term but a turning point. After the solstice, the sun's direct rays begin to move southward, and daylight hours in the Northern Hemisphere gradually shorten. For regions north of the Tropic of Cancer in China, the sun's altitude will gradually decrease after the solstice, while regions south of the Tropic of Cancer will see a decline after the sun directly strikes again.
Post-solstice weather is characterized by high temperatures, high humidity, and frequent thunderstorms. Although the yang energy is at its peak on the Summer Solstice, making it the longest day of the year, it is not the hottest day since the ground continues to accumulate heat.
In ancient times, the Summer Solstice was not only a solar term but also an important folk festival. People would worship gods and ancestors on this day, reflecting their reverence for nature and remembrance of their forebears. To cope with the ensuing summer heat, people consumed cooling foods like Qingbuliang soup, herbal tea, and sour plum soup to cool down. These traditional customs and dietary habits enriched people's lives and carried forward a deep cultural heritage.
