Abstract: Wen Xuan block-printed by Meng and Wen Xuan by Chen Balang in Song Dynasty are two editions well kept up to now. Even though there is much difference between them, they keep consistence in their original text, annotation and dissimilarity from Tang copy. It shows that, in fact, they came from the same Origin which was possibly the earliest wood-block printed edition of Wen Xuan annotated by five-master.
