This book uses time as a clue to describe Song Renzong's life in detail, not only including the joys, sorrows and joys that he experienced as an individual, but also focusing on depicting the many tests that he would face as an emperor. Under the guidance of the Song Dynasty's founding national policy of emphasizing literature and ignoring martial arts, Song Renzong, with his deep understanding of the emperor's role and his gentle and tolerant character, gradually built a relatively benign dynasty operation mechanism with his ministers under his rule. Under this mechanism, the emperor did not take power alone, but ruled the world jointly with the scholars-officials. They quelled the rebellion, carried out reforms, and successively launched many measures to select talents, improve people's livelihood, and improve the legal system. Therefore, in the middle and late period of Renzong's rule, the Song Dynasty's politics, economy, culture, and science and technology all developed by leaps and bounds. It was named as “Jia You rule”. It was also regarded by later scholars as a model for governing the country.
