白居易《李虞部郎中制》目前有元和二年至六年翰林制诰和长庆元年中书制诰两种观点.制文收入白集翰林制诰中,中书制诰说显然难以成立.依据新出土《李夫人韦氏墓志》《李玄堂记》等七方石刻文献,印证传世史料,可知李元和八年春由金州刺史入为虞部郎中,制文内容基本属实,制文即作于此时.此制并非存疑之作,而当为白居易出翰林院后的拟制.
At present,there are two views as to the writing year of Appointment Decree of Li Zeng as Official of the Yu Ministry by Bai Ju-yi,namely,the Hanlin Decree in the second to sixth year of the Yuanhe reign and the Zhongshu Decree in the first year of the Changqing reign.Since this decree was included in the Hanlin Decree of Bai Collec-tion,the theory of the Zhongshu Decree is apparently false.According to the newly unearthed seven stone inscription documents,such as The Epitaph of Wei Shi,Mrs.Li and The Records of Li Zeng's Hall,Li Zeng was promoted from the governor of Jinzhou to official of the Yu Ministry in the spring of the eighth year of the Yuanhe reign.The content of the decree is confirmed,and the decree was made at this time.Therefore,with little doubt,this decree was draf-ted after Bai Ju-yi left the Imperial Academy.
