郭汜
When Dong Zhuo seized power in 189, he wanted to make Zhu Jun his chief assistant, but Zhu Jun refused in protest of moving the capital to Chang'an. Dong Zhuo left Zhu Jun in charge of Luoyang after he headed west for Chang'an. Zhu Jun defected to the coalition forces and moved south in 191 to Jing Province. In the following year, he was defeated by Dong Zhuo's commanders Guo Si and Li Jue. He returned to the imperial court after Dong Zhuo's assassination and served until 195 when he was taken captive by Guo Si, who had by then broken out in open conflict with Li Jue. Zhu Jun fell ill and died soon after. He was noted for being filial and generous to his peers.
