《新唐书·列传·卷八十二》
所以古代拜帅命将，国君虔诚如鄃助成般任命他，又赐给代表朝廷的斧钺仪仗，所以军队的礼节不进入朝堂，朝廷的礼节不进入军营，将领依据战机所采取的适宜的决策不能由遥远的朝廷来裁定。
是以古之遣将者，君推毂而命之，又赐鈇钺，故军容不入国，国容不入军，机宜不以远决，号令不以两从。
Hence, in ancient times when a general was appointed, the sovereign would invest the general with authority as sincere as that given by Duke Cheng of Zhou and would entrust the general with an axe as a symbol of the sovereign’s authority. Therefore, military etiquette did not extend to the court and vice versa. Any decisions made by generals in response to specific developments on the battlefield could not be second-guessed from the distant court.
