Tea whisk , made of bamboo, is a necessary tea set in the "dian cha" of Chinese tea art in the Song Dynasty. The production process of tea is very complex and delicate, and it will break or fail to form if it is not careful. It took Mr. Chen Jinxin eight years to understand the production process of tea. It is his and his father's long-term persistence and slow processing and polishing that made the tea process not be left behind in the long river of history and dissipated with time.
