Thanks to advanced science and technology, we can get paid now without going out. There were no banks in ancient times, but there were institutions specializing in paying wages everywhere. The main financial source of these institutions is local taxes, so even if the transportation is inconvenient, officials all over the country can still get their salaries.
In ancient times, wages were not real money as we are now, but were replaced by necessities such as grain, daily necessities, cloth and spices. In the year of reducing expenses, land will be used to deduct wages. For heavy things like grain, ancient officials usually asked domestic servants to pick them up, or porters at that time to pick them up, which is equivalent to express delivery now.
As for the time of paying salaries in ancient times, different dynasties have different regulations. In the Han dynasty, wages were paid annually; In the sui dynasty, it was issued twice a year; During the Wei and Jin Dynasties, the salaries of officials were paid on a monthly basis, of course, only for posts above the county magistrate.
"Jiaozi" appeared in Song Dynasty, which, like the function of paper money now, gradually changed the way of using grain as salary. In this way, it is obviously much easier for officials to get paid, and it also saves a lot of manpower and material resources, which is a great development in the history of China.
