When will the West Lake Longjing be picked?

Tea picking time is relatively fixed. Longjing tea picked before Qingming Festival is called "Longjing Tea before Qingming Festival", and that picked before Grain Rain after Qingming Festival is called "Longjing Tea before Rain". Among these two teas, "Longjing before Qingming Festival" is more precious, and it is the "noble" in Longjing tea. The first tea (spring tea) must be completed before the long summer, and it takes more than 1 month before and after, and the picking period is short; The second tea was picked in Xiaoman and died a few days behind the scenes; Three kinds of tea are mined in summer solstice and end a few days before the heat; Four kinds of tea, also known as Xiaochun tea, were mined about 10 days before beginning of autumn and closed in Bailu.
