The Confucius, in writing the “Chunqiu“, often took to using rhetoric when uncertain of any taboo to bestow what he wanted to state. Gongyang Zhuan took to deciphering the Chunqiu with historical philosophy by emphasizing on the imperial king, and the greater united thoughts. The former also took to a circumventing technique when faced with those of superior, blood related and elite stature. The Qing period Fong Lu has written in the “He's interpretation of Chunqiu Gongyang Jing, “those who circumvent the taboos often dislike the topic as a thorn, and the deeper the taboo the deeper the thorn, and perhaps when forcing with imperialism, or forcing to humble to the respected, or solicit reward to cover the shortfall, or attribute the blame on the smart and the righteous, a scholar can read his king's mind through loyalty“, where taboo can be read between the lines but not losing its intended meaning. For which, the Gongyang Zhuan took to a concealed methodology that although seemed circumventing but still held true the author's view of the right and wrong, instilling fear in unscrupulous courtesans and thieving individuals to highlight the imperial power. Gongyang Zhuan spread the Confucius teaching through righteous by highlighting the meaning subtlety in the Chunqiu. When it comes to studying methodology, neither symbolism nor rhetoric could be overlooked, but duly addressed. Qian Zhong Shu had presented his unique insight, stating, “the Gongyang Zhuan and Guliang Zhuan showcased the beauty of “subtlety“ in the “Spring and Autumn Annals“, and were regarded as the oldest rhetoric in the Mandarin, ranging from 'hidden meaning', 'unspoken words', or 'subtle words', which were all methodology deployed by the literary set“. Broaching from the rhetoric angle, Qian had presented that the eloquent methodology behind the Gongyuan Zhuan, Guliang Zhuan could serve as the general examples of the methodology behind the Chunqiu. The compiling example of the like of “hidden meaning“, “unspoken words“, or “subtle words“ had all involved the art of rhetoric. The viewpoint of the taboo rhetoric behind the Chunqiu had been deployed to manifest the narration on the just example of the methodology behind the Gongyan Zhuan, in search of fully scrutinize the methodology of subtle suggestion in the Chunqiu. By exploring the taboo rhetoric in the Gongyang Zhuan, combined with examining the “concise text“ in the Book of Songs, an overview on the Book of History how it “mirrored“ history and empirical theorem would validate that methodology, history writing and poetry writing were essentially interchangeable.
