Ojuk is a bamboo that has long been regarded as a sacred symbol of the Chunghyojeongjeol, which has been called jajuk in China and black porridge in Japan. The color of the ojuk is very beautiful and varied, and the surface is also an excellent material that does not require painting. A person who has the skill and ability to make craftwork with these porridge is called Ojukjang.

It is used to cut down bamboo trees that are at least five years old and dry them for more than five years to make bamboo fields, and what can be used as a whole is used to dry them for more than 10 years, so that they do not burst and go bad even after a long period of time.

Ojukjang is a traditional craftsmanship. On December 31, 1996, Yun Byung-hoon was recognized as the holder of the function of Ojukjang, an intangible cultural asset, and was recognized as an honorary holder on April 13, 2017.
