Gate Valve for Thousands of Years

A book tells one thing: **Thousands of years of life and death of Chinese nobles**. Clan clan - those families that rely on blood ties, family education, marriage, and prestige to turn "officialship" into an ancestral craft. They grew up little by little in the officialdom of the Western Han Dynasty, and became the norm in the Eastern Han Dynasty. They climbed to the top of the power pyramid in the Wei, Jin, Southern and Northern Dynasties, were drained by the imperial examination in the Sui and Tang Dynasties, and were uprooted by wars in the late Tang and Five Dynasties. This book does not write about the history of institutions, but about people: how did the old man of a certain family become the Third Duke, how did the son of a certain family catch the baton, how many treasures were found when a certain family was ransacked, and when a certain family fell into decline, even the ancestral graves were dug up.
