other major rebels had also emerged, including: Du Fuwei, agrarian rebel, occupying the modern southern Anhui region. Gao Kaidao, agrarian rebel, occupying the modern extremely northern Hebei region. Liang Shidu, agrarian rebel, occupying the modern central Inner Mongolia region, declaring himself the Emperor of Liang. Li Gui, formerly a Sui official, occupying the modern central and western Gansu region, declaring himself the Prince of Liang. Li Yuan, formerly a Sui official (and Emperor Yang's cousin), occupying the modern central Shanxi region, announcing that he wanted to make Emperor Yang's grandson Yang You the Prince of Dai, then at Chang'an, emperor. Lin Shihong, agrarian rebel, occupying the modern Jiangxi and Guangdong region, declaring himself the Emperor of Chu. Liu Wuzhou, agrarian rebel, occupying the modern northern Shanxi region, declaring himself the Dingyang Khan. Luo Yi, former a Sui general, occupying the modern Beijing region. Xiao Xi, formerly a Sui official, a grandson of Emperor Xuan of Western Liang, occupying the modern Hubei, Hunan, and Guangxi region, declaring himself the Emperor of Liang. Xue Ju, agrarian rebel, occupying the modern eastern Gansu and western Shaanxi region, declaring himself the Hegemonic Prince of Western Qin. Zhu Can, formerly a Sui official, roving with his army in the modern southern Henan and southeastern Shaanxi region, first declaring himself the Prince of Jialuolou, and then the Emperor of Chu. By spring 617, Li Mi and Zhai had captured Emperor Yang's main food storages near Luoyang, the Luokou and Huiluo Storages, thus keeping their army well-supplied while making the Sui forces at Luoyang beginning to lack food. Li Mi took the title of Duke of Wei, while creating Zhai the Duke of Dong Commandery (although Li soon, fearful of Zhai, killed him and seized Zhai's army). A number of other agrarian rebels at least nominally submitted to Li Mi, including Dou and Li Yuan, and it was often thought at the time that Li Mi would soon be able to become emperor. Emperor Yang sent Wang to Luoyang to aid in its defenses, and Li's offensives stalled. Meanwhile, Li Yuan advanced southwest and captured Chang'an in winter 617. He declared Yang You emperor (as Emperor Gong) while honoring Emperor Yang as Taishang Huang (retired emperor), and he himself wielded actual authority over the western Sui commanderies under the title of Prince of Tang. Meanwhile, at Jiangdu, it was said that Emperor Yang's lifestyle grew increasingly decadent.
