陸羽
There are two opinions regarding the origin of the book's name. The first holds that it derived from the opening passage of the work by the Chinese writer, Lu Yu, entitled "Chá Ching" ("Cha-kyo" in Japanese, The Classic of Tea or Tea Classic in English), in which he writes "Tea is a good tree in the south". The alternative view asserts that it came from the name of the original author, Nanbo Sokei.
