Wuwei, Gansu
Modern research into the Tangut languages began in the late 19th century and early 20th century when S. W. Bushell, Gabriel Devéria, and Georges Morisse separately published decipherments of a number of Tangut characters found on Western Xia coins, in a Chinese-Tangut bilingual inscription on a stele at Wuwei, Gansu, and in a copy of the Tangut translation of the Lotus Sutra.
