Abstract: The tea book “Jian Cha Jue” was written by Ye Jun in Qing Dynasty. It was lost in China. Now, there are Baoli and Mingzhi two editions in only a few Japanese libraries. The earliest edition of Baoli was not written by Ye Jun, but supplemented by the Japanese monk Jiao Zhong. The edition of Mingzhi was prefaced by the Chinese Wang Zhiben who was touring in Japan, and emendated by the Japanese Noboru Oda. They deleted the content which Jiao Zhong supplied when reprinted this tea book, but appended seven issues about tea which from Tu Long “Kao Pan Yu Shi”. Because of these, these two editions of “Jian Cha Jue” in Japan are jumbled. According to these confusions, the paper is on the purpose to resolve these problems.

Key words: Jian Cha Jue, Ye Jun, Tea Book
