周書

The package is composed of three volumes, that is, Biographies of Emperor, Biographies 1 and Biographies 2. In 520s, the people of all nationalities in the Huanghe River valley revolted and disintegrated the feudal regime of the Northern Wei in the north China(396-534). In the fierce hierarchy fight, the landocracy built up teams to raise insurrections and fought against each other. Ultimately, two feudal separatist regimes, that is, Eastern Wei( 534-550)and Western Wei(535- 556) were built up in the north, forming a balance of three powers with the government of Liang(502-557). Later on, the Eastern Wei was renamed as Qi (550-577)and the Western Wei was renamed as Zhou(557-581), which is called Northern Zhou by the descendants. And in the south, Chen(557-589) was replaced by Liang.
