Wang Kai (王鍇), courtesy name Zhanxiang (鱣祥), was a chancellor of the Chinese Five Dynasties and Ten Kingdoms period Former Shu state.
It is known that he served as an emissary of Emperor Zhaozong of Tang during the Tianfu era (901–904) to Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan) late in the Tang dynasty, and thereafter remained in Xichuan, which was then ruled by Wang Jian.
[3] In 911, when Wang Jian built a new palace and issued an edict ordering the collection of books, Wang Kai submitted a petition praising the effort and outlining how many emperors in history have used various efforts to collect and encouraged the reading of books.
However, after the Later Tang realm began to be embroiled in a large number of rebellions (over the army's dissatisfaction over Emperor Zhuangzong for not giving soldiers sufficient rewards and over his killing of the generals Guo Chongtao and Li Jilin), Emperor Zhuangzong initially ordered Wang Yan to halt at Chang'an, and then put him and his family to death.
However, it is known that Wang Kai had a large collection of rare books at home, and that he himself had written lengthy commentaries.
