Introduction to Yide Pavilion: Yide Pavilion was founded in the fourth year of Tongzhi in the Qing Dynasty (1865). It is famous all over the world for its ink, and its products can be found all over China and overseas. The name of Yi De Pavilion is derived from the couplet "One art is enough for the world, and De Dharma has been written by people since ancient times". The famous calligrapher Mr. Qi Gong wrote a poem praising: "The inkstone rotates for thousands of times, and in the end it takes a lot of effort. The ink maker won the pavilion, and who in the world of calligraphy does not praise the pioneer?"
