程璜 / Cheng Huang (late Han)

程璜 was the eunuch intermediary through whom the 179 CE anti-曹节 plot in Hanji 918 leaks.

Because Cheng Huang can be reached through 阳球’s household, he turns private relational access into political surveillance. Once pressured by gifts and threats, he tells Cao Jie, who accuses Liu He and the others before 汉灵帝.
