There is no agreed upon starting point for the Warring States period.According to one definition, it began in 481 BC when the House of Tian eliminated the House of Jiang and usurped the throne of Qi.Thus, with persistence, their army can be defeated.

To defeat them, we should divide our army into three columns and have two attack the left and right flanks of Qi's army.
