Dàwáng
Dàwáng was a Tujia native chieftaincy centered on Sanmao in the upper Youshui valley, in present-day Laifeng County. The Yuan established Sanmao Prefecture in 1294.
The Yuan made it a pacification commission ruled by the hereditary Tan clan in 1346. After warfare under the early Ming, Tan Youliang gathered scattered people and restored the office in 1404; it regained commission status in 1406. The Qing abolished Sanmao in the native chieftain reforms of 1735 and established Laifeng County on its territory in 1736.
