During the struggle for power, political groups dependent on imperial power continued to rise, fall, and be reborn. In the process of continuous improvement and strengthening, the absolutist imperial politics produced a large number of vassals: royal family, concubines, relatives, eunuchs, powerful ministers, separatists, vagrants and external forces. They can be a guarantee to strengthen and consolidate the imperial power, or they can be a bomb that creates hidden dangers for the imperial power. They are either benign or malignant. They always accompany the imperial power, covet the imperial power, and go through ups and downs in the changes of political power.
Emperors of all dynasties have all struggled with these major forces. Who is in charge of the ups and downs in this ebb and flow?
