In fall 902, Qian faced the most serious challenge to his rule since he took over the two circuits. He was visiting his ancestral neighborhood in Lin'an, which he had promoted to the status of Yijin Base (). Meanwhile, he ordered his officer Xu Wan, and Xu's soldiers to dredge a canal, a task that Xu and his soldiers, who had previously served under Sun Ru and who fled to Qian after Yang defeated Sun, complained about; despite the advice by Cheng Ji, who was Qian's deputy military governor by this point, to rescind the dredging order, Qian did not relent. While Qian was at Yijin, Xu and Xu Zaisi () started a mutiny and tried to capture Hang Prefecture, which was defended by Qian's son Qian Chuanying () and Ma Chuo. They captured the outer city, but Qian Chuanying and Ma held out against the attack in the inner city. Qian Liu, hearing of the mutiny, had to rush back to Hang Prefecture and only got into the inter city through the siege with difficulty. With the inner city continued to be under siege, there were some suggestions that Qian flee to Zhendong's capital Yue Prefecture, but Qian remained at Hang after advice from Du Leng's son Du Jianhui ().
