Huaiyang initially covered the later Chen, Yingchuan and Runan commanderies and a total of more than 60 counties.
In 196 BC Liu You (劉友), a son of the Emperor Gaozu and the first Prince of Huaiyang, was granted the territory, but was moved to Zhao two years later.
After Qiang's death, the fief passed to his brother Wu (武), who was killed in the Lü Clan Disturbance in 180 BC.
The kingdom/principality was reinstated for a final time in 79 AD, when Liu Bing (劉昞), a son of the Emperor Ming, was granted the fief.
[7] In 2 AD, Huaiyang consisted of 9 counties: Chen (陳), Ku (苦), Yangjia (陽夏), Ningping (寧平), Fugou (扶溝), Gushi (固始), Yu (圉), Xinping (新平) and Zhe (柘).
