围魏救赵

所谓围魏救赵，是指当敌人实力强大时，要避免和强敌正面决战，应该采取迂回战术，然后抓住敌人的薄弱环节发动攻击。

Besieging Wei to rescue Zhao here is to avoid a head on battle with a strong enemy, and instead strike at his weakness elsewhere.

这两部分是围魏救赵的重要铺垫，充分反映了孙膑超群的军事指挥才能和精深的用兵计策。

The two parts are the important foreshadows of surrounding Wei and Saving Zhao, and fully reflect Sun Bin's excellent military talents and his mastery art of war.
