《北大史学》第4期(1997年)发表了我的一篇书评,其中批评了《安史乱后的安西与北庭》一文中的错误。我的批评完全是纯学术的,是针对具体问题的。可是,该文作者薛宗正先生以讨论“唐代西域史研究中若干重大问题”为由,转而牵扯到笔者的其他论著。事涉专门,不辨难明,故草此作答。 Peking University Historiography No. 4 (1997) published a book review in which I criticized the error in the article “An-xi and Bei-ting after An-shi-chaos.” My criticism is purely academic and is specific to specific issues. However, the author of this article, Mr. Xue Zongzheng, talked about other major works of the author in the light of “some major issues in the study of the history of the Western Regions in the Tang Dynasty.” Involved in a special, does not distinguish hard to understand, so the grass replied.
