Which should I read first, Lessons Learned from Mutual Learning or Thinking of Ku Quanshu?

As a Mirror from the Same Resources is a chronicle. Is to use the age as a narrative clue. From the 23rd year of Wei Lie's Zhou Dynasty (403 BC) to six years after the Five Dynasties (959 AD), Zhou Shizong collected the history of Huainan 16 dynasty 1362. It is divided into 294 volumes, about "more than 3 million words", with 30 volumes of textual research and 30 volumes of catalogue.

Sikuquanshu is a series of books. Similar to an encyclopedia. There are more than 3,500 books, 79,000 volumes and 36,000 volumes, about "800 million words". It covers the history of Confucian classics (works of Confucian thinkers) (various historical materials) and works of other thinkers (literary works and literary theoretical works).

Are you sure you want to read through these two books after the introduction? There are database materials on the Internet of Zi Tong Zhi Jian. Sikuquanshu may have to open the database of Beijing Library or National Library to read. Generally, people who do related research have targeted retrieval. As a general study or interest in reading, it is really not suitable. Similar to the above, there are books such as Selected Works of Zhaoming, Yongle Dadian, Taiping Magnolia, and Integration of Ancient and Modern Books. Large-scale, numerous books, mostly books containing various works. Really not a good research object.
