Every change of City Lord required the review and approval of the Ancestral Court, only then could he truly become a local hegemon. This rule was also reasonable, a year's time of governance would reveal much about whether one truly possessed the capabilities of a City Lord. The performance report after a year was also the judgment of the Ancestral Court. It assessed the contribution of the new City Lord to the main city over the past year as well as his personal abilities, and only those with outstanding evaluations could truly inherit the position. Otherwise, another selection would be necessary.
