“Yukou Paper” is a kind of traditional handmade paper in Ninghua, which is located in northwest of Fujian province. “Yu” means jade, because “Yukou Paper” is so pure，white and smooth, just like jade. Currently, there are two interpretations for“Kou”, the first one is the best part of bamboo after stripped. The second one is a measure word in the past, which equivalent to the “Dao”nowadays. In the old days, the Yukou paper was used to write memorials to the throne, account books, deeds, and to print books, genealogies, criptures and archives and historical books.
