《韩非子·奸劫弑臣》
依靠坚车好马，就可以在陆地上冲破陡坡险阻的危险；凭借船的安稳，依仗桨的作用，就可以在水上克服横渡江河的困难；掌握法术之道，实行严刑重罚，就可以成就霸王的功业。
讬于犀车良马之上，则可以陆犯阪阻之患；乘舟之安，持楫之利，则可以水绝江河之难；操法术之数，行重罚严诛，则可以致霸王之功。
Relying on strong cars and good horses, you can break through the dangers of steep slopes and obstacles on land; relying on the stability of the ship and the power of the paddles, you can overcome the difficulties of crossing rivers and rivers on the water; mastering the law and magic, implementing strict laws and severe punishments, you can achieve the merits of a tyrant.
