蘇秦
Su Qin informed the Marquis of Zhao that his territory lay in a crucial position, slightly offset from the other warring states but ultimately disadvantageous. He suggested that because of this, in an alliance with the other powers, the Zhao State would effectively hold the balance of power. Much impressed by the idea, the Zhao ruler rewarded Su Qin financially and invited him to venture forth and discuss an alliance with the other states.
