Abstract: Since The Complete Works of Qian Daxin was published, many scholars have noted plenty
of lost articles in different ancient books and written papers to introduce them. This paper points out that
Record of the Reconstructed Zhumingsi was collected in The Local Chronicles of Suzhou and Preface
of Strategies of the Warring States Period was collected in Series of Shiliju. Through literature analysis,
we can confirm they were exactly created by Qian Daxin in 1793 and 1803. These two lost articles may
contribute to academic research in the area of Qian Daxin’s life and academic thought.

Key words: Qian Daxin, Collected Works of Qianyantang, Record of the Reconstructed Zhumingsi, Shiliju
