《浮生六记》新增补本所收之《册封琉球国记略》,须正名为《琉球国记略》。将它和官书《续琉球国志略》相对照比较,可发现它记载有关嘉庆十三年琉球之行的三个重要日期均有误,且从文风诸方面来看,非沈复之作。其作者很可能是使团中另一位通晓音律的从客。由于他也亲历此行,所述见闻,并非向壁虚造或剿袭拼凑,具有一定的历史和文化价值,但日期之误,须予订正。 “Floating Life Six” added a copy of the “Seal of the Book of Ryukyu States”, should be renamed as “Ryukyu Kee.” Comparing it with the official book, “Continuation of the Ryukyu National Records,” it can be found that it contains three important dates concerning the Jiaqing trip in Ryukyu. All three important dates are incorrect, and from the perspective of the style of writing, it is a non-repetitive work. The author is likely to be another of the envoys familiar with the temperament. Because he also witnessed this trip, the insight and not fabricated or destroyed to the wall pieced together, with some historical and cultural value, but the date of the error, to be revised.
