Cold Dew (Chinese: 寒露) is the 17th of the solar terms of the lunar calendar which fell on Oct 8 and ended on Oct 22 this year. It begins when the Sun reaches the celestial longitude of 195° and ends when it reaches the longitude of 210°. The turn of seasons is obviously felt all over the country after the day of Cold Dew, as the coolness in the early autumn will turn into the coldness in deep autumn. Starting from the day of Cold Dew, it rains less, and the weather is dry with comparatively hot day and cool night. It is the time to get respiratory and digestive diseases easily, as well as cold and fever caused by the turn of seasons. [Photo by Wang Jin/Palace Museum]
