郭泰 / Guo Tai (late Han)
郭泰 / Guo Tai (late Han) enters through Hanji 931 as the reputation witness for 王允 before Wang Yun’s later anti-董卓 role. The episode says Guo Tai praised Wang Yun as having the capacity to assist a ruler.
The page is intentionally narrow. Guo Tai matters here because the host uses his praise to turn Wang Yun’s ambition, classical study, and riding-archery discipline into early 道德名望政治资本, not because the source gives a fuller biography of Guo Tai.
