Sanxia, a renowned Taiwanese tea region with over 200 years of history, began during the Qing Dynasty. It thrived in exporting high-quality black tea during the Japanese occupation. After 1945, it shifted to green tea production, becoming Taiwan's unique green tea region today. Sanxia is famous for its 'Biluochun' and Longjing green teas, while its black and Pouchong teas are also highly regarded. This diverse tea production reflects Taiwan's modern history.
