The Chushu solar term, also called the End of Heat, usually starts between August 22 and 24 on the Gregorian calendar. This year, it falls on August 23. The character "chu" (处) means "to end," while "shu" (暑) signifies the intense heat of midsummer.  

Together, they capture the essence of the solar term: "The heat stops here." The End of Heat signals the start of summer's transition into autumn. However, the summer heat lingers during the day. It is also when, in most parts of China, rainfall eases and the air becomes drier.

Humans have long celebrated this season with folk traditions evolving worldwide. Chinese customs include eating duck, which is believed to help counteract autumn dryness. This is a practical way of adapting to seasonal changes, grounded in ancient wisdom.
