Yang You

Yang You, also known by his posthumous name as the Emperor Gong of Sui (隋恭帝) (605[5] – 14 September 619?

[9] As Emperor Yang did not often stay in the capital Chang'an, starting 613, he made the eight-year-old Yang You nominally in charge of Chang'an, although he left the official Wei Wensheng (衛文昇) in actual charge of the city.

Wei's lieutenants Yin Shishi (陰世師) and Gu Yi (骨儀) were left in charge of the city and guardianship over Yang You.

Quickly, the surrounding commanderies, including most of modern Shaanxi, Sichuan, and Chongqing, submitted to Li.

The duke died in fall 619,[10] and while traditional histories did not directly state so, they implied that he was killed on the Tang emperor's orders.

He had no sons, and his title was inherited by a distant nephew, Yang Xingji (楊行基).
