《旧唐书·列传·卷一百零八》
当时京畿的镇军督将有人倚凭朝廷恩宠或仗恃功劳，经常侵扰官吏和百姓，武元衡颇感苦恼，便称病辞官。
时畿辅有镇军督将恃恩矜功者，多挠吏民。元衡苦之，乃称病去官。
At that time, some of the garrison commanders in the capital relied on the favor of the court or their own merits to frequently harass officials and civilians, which made Wu Yuanheng very distressed. He therefore pretended to be ill to resign.
