Chinese ink sticks are one of the four jewels of study along with brush, paper and inkstone. Underneath the surface of the black substance are hidden workers in workshops without whom one of these treasures of China would not exist. The lack of communication in their workplace is effectively reflected through the silence in the film. Demand is huge, value is high and there is work that needs to be done. This film explores the environment as well as the level of concentration and effort being put behind the product. This film speaks volumes about the lives and work of unsung craftsmen without using a single word.
