一、资料鉴别的必要性。旧时代反动统治阶级的官方文献档案或报刊中所反映的内容大都美化粉饰自己,制造假象,掩盖罪恶,歪曲历史,欺骗民众。旧的地方志不论官修或私人所修,尽管标榜“文以载事,不尚私评”,总离不开统治阶级的偏见,总有封建糟粕充斥其中。而旧时代的史志工作者,因受时代环境、知识水平、自身利害、阶级偏见等局限,一般都做不到秉笔直书。所以,必须严加考证。 First, the need for data identification. Most of the content reflected in the official documents or newspapers and periodicals of the reactionary ruling classes in the old era beautify themselves, create illusions, cover up evil, distort history and deceive the public. The old local records, regardless of official repair or private repair, despite the advertised “text to carry things, not private evaluation,” always inseparable from the prejudices of the ruling class, there are always feudal dross full of them. The historians of the old age, due to the age environment, knowledge, self-interest, class prejudices and other limitations, are generally not upright books. Therefore, we must strictly research.
