《六韬·龙韬·励军》
将帅能同士卒同寒暑，共劳苦，同饥饱，那么全军官兵听到前进的号令就欢欣鼓舞，听到停止的号令就愤怒。
将与士卒共寒暑，劳苦，饥饱，故三军之众，闻鼓声则喜，闻金声则怒。
If the generals can share the cold and heat, labour and hunger and fullness with the soldiers, then all the officers and soldiers of the army will be excited when they hear the order to advance, and will be furious when they hear the order to stop.
