[Problem Solving] Bi Yuan (1730 ~ 1797), whose real name is Qiu Hong, is a native of Lingyanshan, a foreigner, a minister and a famous scholar in Qing Dynasty. There are 220 volumes of Zi Zhi Tong Jian, of which Song and Yuan Dynasties began in the first year of Jianyuan in Song Taizu (960) and ended in the 28th year of Zheng Zhi in Yuan Shundi (1368), and Zi Zhi Tong Jian began in the 23rd year of King Wei Lie Zhou (403 BC) and ended in the 6th year of Xiande in Zhou Shizong (959). The continuation of Zi Zhi Tong Jian inherits Zi Zhi Tong Jian in time and draws lessons from Zi Zhi Tong Jian in style, hence its name. Although "Continued Zi Zhi Tong Jian" is not as long as "Zi Zhi Tong Jian", the Song and Yuan Dynasties are extremely important in the history of China. The Song Dynasty limited the spirit of China people from Guangyuan in the Tang Dynasty to the extreme of "small life and death, big shame", and closed the intellectuals in China to the deformity of arrogance even if they perished. The Yuan Dynasty was a pure alien who entered the China world for the first time, and the ideological changes of the Han literati were worth pondering. Those who are interested in tracing back to history and seeing through the difficulties and obstacles in China today must make a detailed investigation of the Song Dynasty; Those who are interested in identifying the mentality of the Han people under the alien rule of the Yuan Dynasty and uprooting the old moral ideas that have been handed down to this day cannot but study the Yuan Dynasty. Here, we have to browse the history of continuous capital management in Song and Yuan Dynasties as a mirror.
