半发酵的茶统称“乌龙茶”。乌龙茶如今已变得非常有名,关于其语源有若干种说法。只是其名称似乎并不是那么历史悠久。当年曾随亨利的船队来到日本的美国传教士萨缪尔·威廉斯是一位与日本有深厚渊源的人物。他曾对茶做过一番考证。从1832年起有一份在广州发行的英文报纸《中国丛报》,威廉斯曾在上面发表文章。文中说:“乌龙即black dragon,其名号来自一株有名的茶树,这株茶树正是这种茶的起源。” Semi-fermented tea collectively called “oolong tea.” Oolong tea has now become very famous, there are several sources about its source. Only its name does not seem so historic. Samuel Williams, the American missionary who had come to Japan with Henry’s fleet, was a man with deep roots in Japan. He did some research on tea. From 1832 there was an English-language newspaper, The China Journal, published in Guangzhou, where Williams had published an article. The article said: “Oolong black dragon, whose name comes from a famous tea tree, this tea plant is the origin of this tea.”
