函谷関
In 193, Zhu Jun replaced Zhou Zhong () as Grand Commandant () and held an additional appointment as Manager of the Affairs of the Masters of Writing (). In the following year, he was removed from office and reassigned to be acting General of Agile Cavalry () to guard Hangu Pass. In early 195, before Zhu Jun left for Hangu Pass, internal conflict broke out between Li Jue and Guo Si, who started attacking each other in the streets of Chang'an. Zhu Jun remained in Chang'an and was reassigned to be Minister of Finance (). During this time, Li Jue took Emperor Xian hostage to threaten Guo Si, while Guo Si did the same by holding the emperor's subjects hostage to threaten Li Jue. Zhu Jun, Yang Biao and Emperor Xian's other subjects tried to persuade Guo Si to make peace with Li Jue, but Guo Si would not listen. Zhu Jun died of illness within the same year as he could not stand the humiliation of being held hostage.
