函谷関
In 190, Dong Zhuo appointed Chen Ji as the Chancellor () of Pingyuan State (). Before Chen Ji left to assume his new office, Dong Zhuo sought his opinion on relocating the imperial capital from Luoyang to Chang'an, in the light of an invasion by a coalition of warlords from the east of Hangu Pass. Chen Ji objected to this idea. Dong Zhuo was very displeased but he did not harm Chen Ji because of Chen Ji's high standing in the imperial court. Some officials suggested appointing Chen Ji as Minister Over the Masses. When Chen Ji heard about it, he quickly left Luoyang for Pingyuan State to avoid getting caught up in politics.
