Leiyang Bamboo Paper (耒阳竹纸) carries the name of Leiyang, the county-level city on the Lei River that is the hometown of Cai Lun, the Han-dynasty court official credited with inventing papermaking, one of China's Four Great Inventions. The city sits on the southern edge of the Hengyang basin, where large reserves of kaolin and stands of nan bamboo have long supplied the raw material for paper. Leiyang still styles itself the paper capital, and paper production remains one of its industries. The bamboo and the man are both remembered in the landscape: the Cai Lun Bamboo Sea and the Cai Lun Memorial Park keep his name in the city's public places. It is a craft town whose identity rests on a single invention.
