From Qimen County in southeastern China's Anhui Province, a single tea leaf has traveled across centuries to reach the world. Centered on Keemun black tea, a national-level intangible cultural heritage, CGTN examines the 17 traditional processing steps behind the tea's distinctive "Keemun aroma," while also exploring how 5G-enabled smart production lines are revitalizing this craft in the modern era.

From the misty valleys of Qimen to the global stage, a cup of tea moves beyond language and culture. The warmth and balance of Keemun black tea reflect the Chinese philosophy of harmony through tea. More than a legacy of craftsmanship passed down through generations, this Eastern leaf becomes a bridge – connecting people, cultures and shared moments of beauty.
