Wudai Huiyao

Wudai Huiyao is a Chinese historiography book on the Five Dynasties in Chinese history. It was compiled by the Northern Song chancellor Wang Pu, who had personally served the last two of the Five Dynasties, namely the Later Han and the Later Zhou.
After collecting as much information on government systems in the chaotic period as he could find, he carefully examined the material before compiling it into Wudai Huiyao. The work was presented, along with Wang's Tang Huiyao, the Tang dynasty counterpart, to Emperor Taizu of Song. It was published in 30 chapters.
