First, when Yan Song was in the imperial court, Yan Song was a loyal minister at first, but with the expansion of power, after he became a tool of power struggle, everything was not up to him. Yan Song rejected dissidents in order to consolidate his power. From the local government to the imperial court, he has his own people and power. The Yan Party is so powerful that even the monarch can't shake it at will. Also during Yan Song's tenure as cabinet, Yan Dang was very corrupt and took bribes. The local people were forced to pay taxes for many years, and the national treasury faced a deficit problem.
Second, after Yan Song's downfall, Yan Song's corruption during his tenure later led to many irreparable situations. At the same time, Xu Jie and others of the Qing school also seized the opportunity and found a lot of evidence to bring down Yan Song. After the fall of Yan Song, the national treasury was still in serious deficit. Yan Song has a great influence in the local area, and its roots are too stubborn to be uprooted easily. Xu Jie's son occupied a lot of land, and some Qing officials were corrupt.
It's just that a new force has changed in the imperial court, which can't change the disadvantages of feudal society. Emperor Jiajing also indulged in Taoism, built palaces and squandered money, which could not alleviate the deficit of the state treasury at all. Therefore, in this context, Tang Chao's politics is a mess, and power struggles often make people lose themselves.
