Former Shu
In 914, Gao launched his fleet and headed west on the Yangtze, trying to capture four prefectures that were previously part of Jingnan but which had become Former Shu territory — Kui (), Wan (), Zhong (), and Fu (涪州, all in modern Chongqing). However, when he attacked Kui first, he was defeated by the Former Shu prefect of Kui, Wang Chengxian (), and withdrew with heavy losses. In light of Gao's attack, there was suggestions made to the Former Shu emperor Wang Jian that Former Shu destroy a dam on the Three Gorges to let the water destroy Jiangling, but Wang, listening to the advice of his official Mao Wenxi that doing so would kill innocent civilians, did not do so.
