Chai Rong is a kind and cautious man. When I was young, I handled all kinds of affairs for Guo Wei, and I always handled them properly. These Guo Wei are all in my eyes, so I like him very much. Later, Chai Rong studied riding and shooting and cultural knowledge, joined the military world of Guo Wei and assisted him in his work. Later, after the establishment of Guo Wei, Chai Rong was worshipped as a prince. Chai Rong is also a man with wisdom in his heart and verve in his chest. During his reign after he ascended the throne, he knew everything about war and other affairs, and he had plans and strategies in his heart.
When Zhou Shizong Chai Rong died suddenly from overwork, his youngest son Chai Zongxun succeeded to the throne. But in that turbulent era, the weak little emperor was finally pushed around and replaced by others. At this time, Zhao Kuangyin immediately appeared as the leading role. In the late Zhou Dynasty, because Zhao Kuangyin had been working beside Chai Rong, his ability was appreciated by Chai Rong, and he was later appointed as a general. So now it seems that without Chai Rong's support, Zhao Kuangyin's talent would not stand out so quickly. After the little emperor succeeded to the throne, Zhao Kuangyin led an army to resist the invasion of the Khitan, and then there was a mutiny in Chen Qiao, and Zhao Kuangyin became the later Song Taizu.
The rulers of the two dynasties, Chai Rong and Song Taizu, inherited and applied the general plan of governing the country and army building in the Chai Rong period in the Song Dynasty. It can be said that the last week of Chai Rong's governance was a solid foundation for the prosperity of the Great Song Dynasty.
