Today, Frost’s Descent#

Today is Shuāngjiàng（霜降） in China’s 24 solar terms — the last solar term of autumn.

It usually falls around October 23 in the Gregorian calendar. On this day, the sun’s direct rays have continued their southward shift from the equator to about 11°28′ south latitude; in traditional Chinese solar-term reckoning, the sun reaches celestial longitude 210°.

From this point on, the balance of heat tips toward “loss” — the day-night temperature gap widens, and it gets colder by the day.

From Yang to Yin#

In Chinese yin-yang philosophy, Frost’s Descent marks the turn from yang to yin: the weather shifts from cool to cold. The ancients had a line that describes this solar term perfectly:

阴始凝也，凝而为霜。 The yin begins to condense; condensing, it becomes frost.

It means the cool air starts to solidify — frost, snow, and ice all come about this way.

And it’s from this moment that all things begin to prepare for dormancy, storing their yang energy within (keeping their energy deep inside).

Eating in Step with the Season#

This lines up perfectly with how we live: when the cold sets in, we naturally crave high-calorie food, or reach for a stronger spirit to warm ourselves.

If you understand how the shift of yin and yang shows up in the weather, maybe you’ll understand why Chinese people love drinking warm water — haha.

Friends in the Southern Hemisphere are enjoying spring, while those of us up north, remember to dress warmly.

See you next time.
