Why did Biluochun choose to hold the best tea party before tomorrow?

The authentic tea of Biluochun is located in the East and West Mountains of Suzhou, but Suzhou usually enters spring at the end of February, when Biluochun tea trees are growing. Influenced by the local climate and environment, the time of spring in the East and West Mountains of Suzhou will be earlier, so Biluochun will grow better under the influence of intercropping fruit trees. In the solar terms, before the Ming Dynasty generally refers to Tomb-Sweeping Day, but in the local area, there is more rain during the Qingming period, so the tea before the Ming Dynasty can be more affected by the sun, soil and climate conditions, and it is fuller and smoother. Once it enters after tomorrow and before rain, the overall quality of tea will be affected. Therefore, tea before the Ming Dynasty was always more expensive than tea before rain, which originated in Biluochun, Fiona Fang, Zheng Da.
