Qingming, the fifth of the twenty-four solar terms, is the beginning of the dry branch of the calendar month; the time point is around the first day of march in the lunar calendar (April 4-6 in the Gregorian calendar), when the sun reaches 15° of the ecliptic longitude. Also known as "March Festival" or "Green Festival".

"The Seventy-Two Waiting Episodes of the Moon Order": "The March Festival... At this time, everything is clean and clear. ”

"Hundred Questions of the Age": "All things grow at this time, they are clean and clear, so it is called clarity." ”
