What is tea before rain and after rain?

Before the rain, that is, before Grain Rain, that is, after April 5 to April 20, tea making is called before the rain. Although tea before rain is not as delicate as tea before tomorrow, because of the high temperature, the buds and leaves grow relatively fast and the accumulated inclusions are rich, tea before rain is often fresh and durable. Xu Cishu in the Ming Dynasty said that "Qingming is too early, long summer is too late, and before and after Grain Rain, the time is moderate." Qianming tea is fried with tender buds picked in front of Tomb-Sweeping Day. Qianming tea is the top grade of West Lake Longjing, because its tender buds are like the core of lotus seeds, also known as lotus plumule. Before the rain, Chaze was a bud picked in front of Grain Rain after the Qingming Festival, also called Chuncha, which was the top grade of Longjing in West Lake. In addition to the tender buds, there are one bud and one leaf or one bud and two leaves. A bud of tea leaves soaked in water is like an ancient gun with a big flag, called a flag gun, while a bud of tea leaves is like a sparrow's tongue, called a sparrow's tongue.

After Grain Rain collected the tea after the rain, the leaves of this kind of tea were already very big, and the taste of the leaves masked the taste of the buds, which was bitter and more suitable for the elderly.
