What is Longjing before rain?

Longjing before Rain was created before the solar term "Grain Rain". Usually, before Grain Rain, it was time for tea trees to "shoot a leaf", commonly known as "one flag and one cannon", which was used to make Longjing tea. As Hu Jiao said in a poem, "chalcedony is the freshest spring tea before it is cooked in Grain Rain in the morning."

However, after Grain Rain, things got worse. Tea farmers in Longjing have a saying: "Picking three days early is a treasure, and picking three days late is a natural grass." Because it is related to the tenderness of tea.
