Among Yao Cha's old manuscripts left to Yao Silian, there were fewer that could be used for writing the history of Chen than for the history of the Liang. When Yao Silian wrote Chen Shu, he mainly referred to the writings by Lu Qiong, Gu Yewang, Fu Ying and others. Attention should be paid to the general remarks written by Wei Zhi for Liang Shu and Chen Shu. When Emperor Taizong wrote a letter to repair the history of Liang, Chen, Qi, Zhou, Sui and Five Dynasties, Fang Xuanling and Wei Zhi were the directors, and all the history summaries were made by Wei Zheng. The general introduction of Liang Shu is at the end of Volume 6, Emperor Ji. The general introduction of Chen Shu is also at the end of Volume 6 Emperor Ji, and in addition, at the end of Volume 7 Biography of Empress, he added historical facts to the romantic life between of Chen Shubao, Zhang Guifei and others. Reading the general remarks written by Wei Zhi can be used as a reference for grasping and analyzing the history of the Liang and Chen dynasties from a macro perspective. Generally speaking,
Wei Zhi's (魏徵) knew more about Chen dynasty politics than Yao Cha and Yao Silian, which is largely due to the fact that the former commented on history from the perspective of politicians. However, in terms of style, Wei Zhi's historical theory still follows the parallel prose of the six dynasties (Liang, Chen, North Zhou, North Qi, Sui, Tang). However, Yao Silian and especially Yao Cha used prose (散文) in historical theory in the era when parallel prose (骈体文) is popular, which is the place where their style of writing exceeds that of Wei Zhi, and it also had an impact on the rise of ancient prose movement in the middle Tang dynasty. Moreover, there are many facts that were glossed over in the Chen Shu, either out of being afraid to add them or other reasons. A typical example is the biography of
Liu Shizhi (刘师知), which makes no mention of Liu Shizhi helping Chen Baxian rise to power. Such facts have been included in the
History of the Southern Dynasties (《南史》). As for the laws and governance of the Chen dynasty, these are included in the annals of Sui Shu. In general, the
Book of Sui wrote about the evolution of the laws and regulations of the five dynasties of Liang, Chen, Qi, Zhou and Sui, which has been essential to historians in understanding the history of these five dynasties. == See also ==
