Murderous Demon

The vassal states created by Wester Zhou were of varying sizes, and according to the historical records, there were five levels of feudal nobilities, which, in descending order, were: Dukes, Marquises, Counts, Viscounts, and Barons.

Below these five levels were subsidiary states. Their territory was smaller, and they were normally subordinate to larger vassal states. Gui Man was a Marquis, and the State of Chen was one of the 12 vassal states that had a great impact from Western Zhou to the Warring States period.

However, during its middle to later stages, it started to go into decline. It first experienced three internal conflicts and was then destroyed twice. It was then revived, but in the end, King Hui of Chu killed Chen Mingong, resulting in the final destruction of the State of Chen.

Gui Man was enfeoffed in 478 AD, and the State of Chen lasted 25 generations, which spanned 645 years.
