With the support of Gahou, the governor of Wa Province, Shoukou had overtaxed the people of Shisui at 70%. Failure to pay the entire tax in full by any citizen would result in the citizen's entire family being executed. Any opposition was brutally surpressed; Shoukou was known for ordering entire villages to be burned down to punish the people.
