Song Wendi and Liu Yilong inherited his father's conscientious policy of governing the country, cleaned up the household registration on the basis of the righteous act of the Eastern Jin Dynasty, ordered the people to forgive the "rent-and-lodging debt" owed to the government, and implemented a series of measures such as persuading students to study, developing agriculture, and recruiting talents, which enabled the broad masses of people to recuperate and greatly developed social production. According to historical records: "In the past 30 years, the people have made generous sacrifices, ending with the annual tax. Going out early and returning late is just a matter of self-care ... people have connections, and officials have no income. Families give people enough ... where there are hundreds of households, there are cities, there are songs and dances, and groups of people contact each other, which makes the Song Dynasty extremely prosperous. " To be sure, the Yuan-Jia period (424-453) was a historical period with the strongest national strength and people living and working in peace and contentment.

There are many biographies and chronicles to explore this history, such as Southern History, Northern History, Zi Tongzhi Jian, etc. Among them, there are many famous literati and military commanders in Yuanjia era. Although their fate is close to "tragedy", their flying style and grand words are enough to show the outstanding figures in Yuanjia's world.
