魏晋以来学术重南轻北。至隋代,随着全国政治统一,南北学术开始合流,但尚未形成统一的指导思想。而初唐的文化整合却理性得多,提出了“各去所短,合其两长”的方针。从《五经正义》所选用的传注来看,与东晋以来的南学取向一脉相承。但从其所据义疏来看,诸儒在整合中表现了平衡南北的努力。与其他几部《正义》多取南学不同,惟《毛诗正义》更多明显的北学倾向,这不仅纠正了魏晋以来的学术偏向,而且有力的引领了有唐一代的学风。 Since the Wei and Jin academic heavy south light north. Up to the Sui Dynasty, with the unification of politics throughout the country, North-South scholarship began to merge, but no unified guiding principle has yet been formed. However, the cultural integration in the early Tang Dynasty was much more rational, and put forward the principle of “each goes by the short and the two longs”. From the notes selected for “Five Classics of Justice”, the Southern Learning orientation has the same strain as the Eastern Jin Dynasty. However, from the perspective of its righteousness, all the Confucianists showed their efforts to balance the North and the South in the integration. Different from several other “just” schools, South Learning is more different. However, there is more obvious Northern tendency in “Mao Shi Zheng Zheng Yi”. This not only corrected the academic bias since the Wei and Jin Dynasties, but also led the study style of Tang Dynasty.
