Li Xiaogong
Around the same time, the Tang official Li Jing had offered 10 strategies to destroy Liang to Li Xiaogong. Li Xiaogong relayed them to Emperor Gaozu, who accepted them. In spring 621, Emperor Gaozu made Li Xiaogong the commandant at Kui Prefecture (夔州, modern eastern Chongqing) and had him build a large fleet and train sailors to prepare for the attack against Liang. He also made Li Jing Li Xiaogong's deputy.
