一、并非离题万里的开头无须匆忙地阐释“雅”与“俗”的含义，先扫视一下文化历史的长河，不妨从“三千弱水”之中取它“几瓢饮”：其一，佛教初入中国，艰深的佛经使佛教的传播受阻。于是，寺院的僧人们变佛经原文为俗讲，是为变文；将佛教故事制成图像，按图演述，是为变相? First, not the beginning of a thousand miles without having to rush to explain the meaning of “elegant” and “vulgar”, first glanced at the long cultural and historical history, may wish to take it from the “three thousand weak water” Buddhism first entered China, and the difficult Buddhist scriptures blocked the spread of Buddhism. As a result, monasteries in Buddhist monasteries have become Buddhist scriptures to explain vulgarity as vocabularies; making Buddhist stories into images and depicting them in the same way is disguised?
