The beginning of feudal society in Europe was marked by the demise of the Western Roman Empire (476) and the barbarians' stepping onto the historical stage. The feudal factors within the empire-the emergence of slave owners and the invasion of barbarians contributed to the demise of the empire.
The feudal society in China began in 475 BC (Warring States Period).
So the feudal society in China was 950 years earlier than that in Europe.
