In the 24 solar terms, this is the last autumn term, frost descent. The name originates from summer gradually ending, the nights become longer, and vapour gathers as cold weather ascends. Although this is not as common in Taiwan plateaus, you may be able to discover it once!
In aerology, this is not such term as the descent of frost, yet in chinese characters there is a lot of characters with 「雨」such as 「雪」、「雹」 having the meaning of coming down from the sky「由天上降下來」的意思，Therefore people believe frost「霜」comes down from the sky. Dew and frost are both formulated based on the gathering of vapour. Although it may not be obvious in Taiwan, the leaves begin to tern red and weld. A good time to enjoy the autumn scenery.
Remember to seize the day for a longer meditation sit! The solar terms are a good time to practice meditation!
