Qingming: Tomb Sweeping Day and Tea

Qingming is a Chinese holiday on the 15th day after spring equinox.  You may be more familiar with it referred to as  "Tomb sweeping day".   Every year Qingming coincides with a considerable drop in price in some green teas.  Basically, it's because of the rains, but the line is drawn on this day:  the green teas made from leaves picked before this date are given the prestigious "pre-gingming" designation.  The teas picked after the festival (having a much lighter and subtler aroma) will have a lower price tag.
