Yinzhou Rush Grass is a geographical indication certification trademark.

　　Rush grass, also known as mat grass, is an annual plant belonging to the Juncus genus of the Centrolepidaceae family within the Poaceae order. Among them, Chinese mat grass has thicker stems, a greener color, is more brittle in texture, and has a denser core; Japanese rush grass has slender and soft stems, a tough texture but a looser core, with a light green color. Rush (mat) grass is long, straight, and uniform in thickness from top to bottom, with a pointed tip, smooth and awnless, and the entire plant is rich green. The *Yinxian General Annals* record: “Its stem is round and long, with a white pith inside as soft as cotton, which absorbs liquids well and is highly elastic. When woven into mats, it can hold threads without exposing them.” Therefore, rush (mat) grass products are fragrant, with suitable firmness, good elasticity, strong tensile resistance, and offer features such as regulating humidity, keeping moderately dry in summer, and providing good thermal insulation in winter.
