Su Weidao's biographies in the Old Book of Tang and the New Book of Tang both stated that he died at the age of 57, shortly after he was made the secretary general at Yi Prefecture for the second time. The Old Book of Tang further indicated that this commission was shortly after his brief demotion to be the prefect of Mei Prefecture, which in turn was described to be "early in the Shenlong era" (705–707) and be on account of his having flattered Wu Zetian's lovers Zhang Yizhi and Zhang Changzong, who were killed in 705 in a coup that overthrew Wu Zetian. This implies that these events occurred in 705, but does not conclusively establish this. See Old Book of Tang, vol. 94 "舊唐書 列傳 卷四一至五十". Archived from the original on 2008-02-10.
