This version was produced only briefly in the early 1970s, featuring a rare thick white textured wrapper printed with large rectangular Zhong character. The larger cakes, made with coarser leaves, represent the final batch by the Menghai Tea Factory to use antique tea materials, while also being among the first to adopt experimental fermentation techniques. The tea reveals camphor and subtle medicinal notes, preserving classic character reminiscent of Yin Grade Pu-er.
