The Start of Autumn or “Liqiu”, is the 13th solar term. It usually arrives around August 7-9, and the arrival of the Start of Autumn indicates the end of summer and the beginning of a fruitful autumn. Although the Start of Autumn symbolizes the approach of fall, it's not to say that the hot summer days have come to an end. After the Start of Autumn, the warm weather will last for another 30 days, giving this solar term the alternative name "Autumn Tiger."
