吕留良赠吴孟举北游诗的写作年代问题

Probe into the Definite time that Lv Liuliang Writing Poetry for Wu Mengju's going to the North

吕留良《何求老人残稿》卷五有《送孟举北游》二首、《临行余以背疮作恶不得执手》《九日怀孟举》《孟举以诗见寄次韵奉怀》二首。这些诗均作于吴孟举第一次北游京师之年。俞国林《吕留良诗笺释》把上述四题六首诗的写作年代,均认定为康熙七年(1668)。其实俞先生有误判之嫌。吴孟举第一次进京时间应为康熙九年(1670)秋,吕留良赠吴孟举北游四题六首诗当作于康熙九年(1670)秋冬。

Lv Liuliang wrote several poems when Wu Mengju visiting Beijjing for the first time.Yu Guolin firmly believed that the four poems were all completed in the Seventh year of Kangxi.Yet Mr.Yu committed a mistake,for it is in the fall of 1670,the ninth year of Kangxi,that Wu Mengju went to Beijin.So the four poems about Wu Mengju＇s visiting the north should be completed in the fall or winter in the ninth year of Kangxi.
