唐末五代，君弱政乱，武夫悍卒把持朝政，专横地方，吏治大乱。这种混乱局面不改变，就谈不上国家的治理，更谈不上国家的统一和富强。因此，宋太祖即位后，下了很大的决心和力量整顿吏治，重振封建王朝的威望。 ( In the late Tang Dynasty and Five Dynasties, the king was weak and chaos prevailed, powerful generals controlled the court and acted arbitrarily, the country was in chaos. If such situation could not be changed, it was useless to talk about the governance of the country, not to mention the unity and prosperity of the country. Therefore, when he ascended the throne, he made great determination and power to rectify the official to revive the prestige of the feudal dynasty. )
