The living standard of many people is the most direct reflection of the level of social and economic development. Most of the existing works reflecting the living standards of the people in the Song Dynasty are freehand brushwork, and most of them are expounded in the way of class opposition; It equates landlords (exploiters under the traditional concept) with rulers, and peasants (exploited small farmers under the traditional concept) with the ruled; Moreover, the internal logic is that the rulers are above and live in luxury, and the ruled, especially the lower peasants, live a life of hunger and cold; However, the group with the largest number between the luxury floor and the belly floor has little interest; Moreover, such extreme stratification does not show the comparative characteristics of past dynasties at all. No matter the pre-Qin or post-Qin situation, it always feels like such a similar extreme pattern, and it implies an idea of restraining the rich and promoting the poor. It seems that the rich are deprived and the poor are deprived; I don't care about people's intelligence. In fact, for the rich and the poor, the restrictive factors should include the social system and people's own intelligence, but everyone has different opportunities to get rich under different systems. Nevertheless, people's chances of getting rich are directly proportional to their intelligence. It's just that the more unreasonable the society is, the smaller the proportional coefficient is. In view of this, the author wants to show the life at that time as vividly as possible by investigating the prices, official salaries, military salaries, labor remuneration and the daily life of ordinary people in various periods of the Song Dynasty. The so-called "vividness" means that through the author's research results, readers can have a very intuitive impression of the living standards of the Song Dynasty compared with modern times. For example, in the minds of modern people, what is the concept of consistent currency in a certain stage of the Song Dynasty? What kind of modern concept is wealth at a certain stage? Only in this way can the fleshy social life history be presented to readers.
