Why do you say "almost all?" This is because there is a Song Renzong in the middle. If Renzong also earns a monthly salary of 1200 according to the regulations, but he develops his own style, he will give up voluntarily. So who paid the salaries of these emperors and how did they pay them?
For example, people like Song Like Taizong and Song Zhenzong, as emperors, are really inconvenient to fill out the payroll in person, so the monthly 1 200 penetration has always been "left warehouse". So if it is official, the emperor's salary is actually paid by Zuo Zangku.
What kind of organization is Zuocang Library? Zuoku appeared in Sui and Tang Dynasties. It is a subordinate institution of Taifu Temple, which is mainly in charge of human wealth, so Zuoku is used to store human wealth. There was no Taifu Temple in the early Song Dynasty. After the Five Dynasties, there were three divisions: Salt and Iron Division, Du Zhi Division and Household Division.
Let these departments manage the state finances. Zuocang belongs to the third company. Add right warehouse and inner warehouse to monopolize salt and iron. Moreover, it is specially responsible for the management of expenditure surplus, household tax, Huang Zhuang rent tax, local governors' tribute and the centralized revenue and expenditure of money and goods brought by various monopolies.
So which of all the inputs belong to the left repository management? Huangzhuang tax, local tribute and some monopoly income presided over by the court are all managed by Zuoku. In fact, most of Zuocang's income comes not from other channels, but mainly from monopoly.
Monopoly things are salt, iron, tea, wine and the like, which make a lot of money. But these things only belong to the * * * finance, not to the court finance, so even if the monopoly income is more, it can't be classified as Zuoku, and the monopoly goods that Zuoku can use are only land.
So what is the wealth in Zuo Zangku used for? In fact, there are also aspects that need to be managed. The property of Zuocang is mainly used to pay subsidies to Beijing officials and also to pay the military salaries of the imperial army. The most important thing is to pay the living expenses to the prince, princess and empresses, as well as the salary to the emperor.
