This was the first brush with worldwide fame for Taiwan oolong tea. After the Japanese occupation, demand in the world tea market led to the planting of large amounts of black tea in Taiwan's main tea production areas of Taoyuan, Hsinchu, and Miaoli. However, prior to WWⅡ, semi-fermented oolong and pouchong (baozong) were still the main export products.
日據時代以後，由於世界茶葉市場的需求，北台灣桃竹苗為主的產茶區開始大量種植紅茶，二次大戰以前，紅茶、半發酵的烏龍、包種茶是出口大宗。
