White Dew, or Bailu in Chinese, is the 15th solar term in the traditional Chinese calendar, which falls on Saturday this year. White Dew indicates the real beginning of cool autumn. Temperatures gradually go down and vapors in the air often condense into white droplets on the grass and trees at night. During this period, the daylight hours become shorter, and some plants start to turn yellow and red. (Produced by Sun Tianren, Lin Yuan and Zou Yun)
