The traditional Chinese calendar divides a year into 24 solar terms. Bailu, the 15th of the 24 solar terms in the Chinese Lunar Calendar, falls on September 7 this year.
Bailu, or the white dew, is the real beginning of cool autumn. Certainly, the dew is an important element for this solar term. As the temperature declines gradually, water vapor in the air will condense into dew on plants after sunset.
Unlike in the summer, dew drops during Bailu can stay longer during the morning, as the temperature is still low enough to resist evaporation. This phenomenon was observed by ancient Chinese; hence the dew became part of the solar term's name.
ECNU campus is hustling and bustling once again as students are back and classes are starting up. Wishing all ECNUers a happy new beginning!
