从史籍上看,杨隋一代,牛弘在上献书之策、制礼作乐、论议明堂、修定刑律等方面,为隋朝的文化典章制度建设做出了突出的贡献,并从而对承接隋制的唐朝影响颇为深远。其原因有个人、时代与作为关陇集团核心代表等方面因素。这却鲜为人知,十分遗憾。 From the historical point of view, Yang Sui generation, Niu Hong in the policy of offering books, courtesy and music, on the Ming Hall, revised the criminal law and so on, for the Sui Dynasty cultural dictatorship system made outstanding contributions, and thus The Sui Tang system to undertake far-reaching impact. The reasons for this are individuals, the times and the factors that are the core representatives of the Guanlong Group. It is little known, very sorry.
