Biography
Historical sources don't share much information on the eunuch Han Kui. In the sixth month of 185 A.D., which is late July or early August, Han Kui and eleven other eunuchs were enfeoffed as full marquises for their good work against Zhang Jiao and the Yellow Turbans.

It is likely that Han Kui was part of Zhang Rang's influentious faction.
