自陆羽《茶经》问世，茶事方大行其道。茶事厅借助茶叶各部位标本、图片、文字等手段，展示了历代茶人摸索和积累的有关茶树的种植、采制、保存、品鉴、应用等知识以及因茶而创作的各类茶事文艺。在该厅，还利用多媒体手段记录并展现了国内外领导人、国家元首及政界、文化界等各界人士访问博物馆的珍贵照片和墨宝，作为茶博财富珍藏和共享，以茶结缘，甘传天下。
Since Lu Yu’s “Book of Tea” was published, tea-related matters have become extremely popular. By means of specimens, pictures and texts of different parts of tea leaves, the Hall of Tea Knowledge displays the knowledge related to tea tree cultivation, tea-leaf picking, storage, tasting and application of tea explored and accumulated by tea men in past dynasties as well as various tea-related culture and art created for tea. In the Hall of Tea Knowledge, precious photos and treasured scrolls of calligraphy or paintings taken or created when the Chinese and overseas leaders, heads of states and personages of all circles including political circles and cultural circles etc. visited the museum are recorded and displayed by multimedia means. They serve as a treasure of the Tea Museum to be kept appropriately and shared with others. Form ties by means of tea; spread the fragrance all over the world.
