In this solar term, the sun moves from Cancer to Leo (longitude 135). Looking at the sky at night, you can see that the bucket handle of the Big Dipper points in the direction of Tiangan "Shen" (southwest). The day when it was handed over to beginning of autumn was July of the lunar calendar, which was also called "Shen Yue Day". In beginning of autumn, the sun is at the declination of+16 19', which is much more southerly than the +23 26' in summer solstice, so the daytime in Beijing is shortened to 14 hours and 04 minutes (15 hours in summer solstice).

The weather is still very hot. After beginning of autumn, there are still "crouching" and "autumn tigers" still exist. So we should pay attention to heatstroke prevention. However, a leopard cannot change his spots. There is a "beautiful day" when it is hot at noon and cool in the morning and evening, and "one autumn rain is cold and ten autumn rains are frost."
