Last updated 2026-11-12 — Located south of Zaojiaolin Village in Xiaoziling Township, at the point where the Yong and Heng rivers are about to converge. It stands 10 meters high and has a circumference of 400 meters, making it quite prominent. In 1979, during infrastructure construction by the Pioneer Machinery Factory, the tomb mound sustained slight damage. This tomb was mistakenly rumored by locals to be Cao Jiao’s Mausoleum, which led to the village being wrongly renamed Caojiao Ling Village. The Qing Dynasty Guangxu-era Qishan County Annals corrected this: “There is no historical record of Cao Jiao ever coming to Qin. Perhaps because the names ‘Zaojiao’ and ‘Caojiao’ sound similar, the confusion arose. In recent years, local farmers plowing the fields in front of the tomb unearthed a memorial stele, which identified it as the tomb of Left Communicator of the Censorate Yang Gongzu (i.e., Yang Xian) and his wife Lady Huo, thereby confirming the error regarding Cao Jiao.” The stele was once housed in the Zhang family ancestral hall of the village but went missing at an unknown time. Despite the clarification made in the Guangxu Annals, most locals remain unaware, and the erroneous name persists to this day.
