《醒世恒言》卷28“吴衙内邻舟赴约”本事最早来源于明吴大震《广艳异编》卷8《彩舟记》。而“吴衙内邻舟赴约”把《彩舟记》中人物活动地点即运河沿线的地名改为长江沿线的地名,是因冯梦龙把故事发生的时间由明代改为宋代。明代运河路线与北宋有较大差别,《彩舟记》中提到的运河沿线地名不能照搬到“吴衙内邻舟赴约”中,于是冯氏把地点改为历代变化不大的长江沿线城市,而仓促更改后又引出了宋明地理、官制的错误。可见冯梦龙编创“三言”带有明显的商业操作痕迹,追求商业利益的同时也损害了作品的真实性。 “Awaken the common saying” Volume 28 “Wu Yanei oar boat ” the ability to come from the earliest Ming Wu earthquake “Guang Yan different series” Volume 8 “Cai Zhou Ji.” The “Wu Yanei neighborhood boat ” to the “Cai Zhou Ji” character locations that is along the name of the canal along the Yangtze River to change the place names, because Feng Menglong the story changed from the Ming Dynasty to the Song Dynasty. The Ming Dynasty Canal route and the Northern Song Dynasty have a greater difference, “Cai Zhou Ke” mentioned in the names of the canals along the canal can not be copied to the City, and hurried change leads to Song Ming geography, official error. Visible Feng Menglong create “Sanyan ” with obvious traces of commercial operations, the pursuit of commercial interests but also undermine the authenticity of the work.
