The lowest are barefoot warriors and rural scholars, with an annual salary of five stone meters and two yuan a month. A Japanese stone is similar to that of China in the Ming Dynasty, about198kg. During the Edo period in Japan, the peace of four coins was 1 gold. 1 two gold = a small golden sentence. 10 two gold = a gold medal. Samurai's income consists of three parts: knowing and doing, Mi Lu and support money. Knowing and doing is land tax, Mi Lu is rice, and support money is a subsidy given by generals or Daming and princes. In addition, sometimes some extra "rewards" are given, such as year, festival or name, princes' birthdays, weddings and childbirth. Generally speaking, in the early edo period, samurai lived a very rich life. However, in the middle and late Edo period, in order to suppress the strength of governors, the shogunate asked them to "please" and "work". The vassal's financial resources deteriorated rapidly, even making ends meet. As a result, after many governors' finances deteriorated, Daming and the governors had to reduce their salaries or "fold by half". As a result, the living standards of many middle-and lower-class warriors also deteriorated seriously, and many middle-and lower-class warriors later became the main force of "reverse curtain reform"
