Worm once said that the setting of the Chu Dynasty was largely based on the Song Dynasty. When writing about money here, the insect also thought about how to write, the financial system of the Song Dynasty was copper-based, and copper money was the most basic means of circulation, but considering that gold and silver were more familiar to everyone, and it was easier to accept, so the insect was in the previous description, and the silver tael was regarded as the most basic circulation unit.

However, in the comment area, some readers pointed out that the Song Dynasty used copper coins as the circulation unit, and since Chu used the Song Dynasty as a template, copper coins should be regarded as circulation units. When Bug and other readers discussed, they also thought that although it was a completely empty history, it was better to regard copper coins as the basic currency in circulation, at least it looked more rigorous, and with reference to the opinions of all parties, Bug had changed all the places mentioned above to "Guan". In the future, "guan" and "wen" will also be used as the basic monetary units. Please forgive me for the inconvenience caused by the revision before and after the revision.

The following is some of the information that Worm looked up before writing "Rebel Minister". After simplification, it will be turned into some simple formulas for your reference.

Mr. Huang Renyu, in the sub-volume "Song" of his "Great History of China", mentioned that the conversion is based on the assumption that 1 tael of gold = 10 taels of silver = 10 guan = 10,000 yuan, although the mutual exchange rate of gold, silver and copper has been fluctuating, but this assumption should basically be reasonable. In addition, when the Song Dynasty was financially tight, there were 800 Wen and 850 Wen as the same situation. In addition, there are disguised inflations such as two cents, three cents, and ten cents, but these will not be covered in this book.

According to the price level at that time, and some information, the currency of the Song Dynasty was converted into RMB in terms of purchasing power, which is about: 1 tael of gold = 3,000 yuan; 1 tael of silver = 1 copper coin = 300 yuan; 1 copper coin = 0.3 yuan.

Judging from the specific examples on the Water Margin, this rate is also relatively reasonable. In the fifteenth time, when Wu Yong went to persuade Sanruan to join the gang and rob the Shengchengang, Wu Yong asked Ruan Xiaoqi to buy an urn of wine, twenty catties of raw and cooked beef, and a pair of big chickens for one or two pieces of silver. It's almost like a tael of silver for 300 yuan. In addition, in the tenth Lin Chong Fengxue Mountain Temple, when Lu Qian entertained Guan Ying and the errand in Li Xiaoer's shop, he took out one or two silver, ordered three or four bottles of good wine, and served the dishes casually. Similarly, in the forty-fourth time, when Dai Zong and Yang Lin invited Shi Xiu to dinner, Yang Lin threw out a tael of silver and asked the store to serve wine and food casually. Generally speaking, in an ordinary small restaurant, 300 yuan for three people to eat, you can indeed order food casually.
