Preventing the collapse of the Han Dynasty - with Maya

As advisors to the Han Dynasty,  we would intervene right before Han Wudi started to look for more land in the west.  The war with the Xiongnu was expensive and led to severe tax increases which in turn led to banditry and rebellion within the Han Dynasty. By convincing Han Wudi to abandon the pursuit of capturing western land, we could have prevented the war that led to the demise of the Han Dynasty.
