Abstract: The short article titled “Records of the Renshu Building”, which is compiled in the third volume of Qing Yuan Zhi Lue, is very important to understand the thought of oldage FANG Yizhi. Professor YU Yingshi has punctuated this article in his book of An Examination of FANG Yizhi’s Integrity in His Later Years (FANG Yizhi Wanjie Kao)，but those punctuation marks still have some errors. In addition, some historical data have proved that FANG Yizhi was a teacher and a good friend of ZUO Cangyi, who was just another interlocutor of “Records in the Renshu Building”

Key words: YU Yingshi, FANG Yizhi, ZUO Cangyi, Records of the Renshu Building, An Examination of FANG Yizhi&rsquo, s Integrity in His Later Years
