What are the differences and connections between the powerful landlords, the gentry, the gate valve and the aristocratic families?

Powerful landlords: It was in the Eastern Han Dynasty that Liu Xiu was born and fell in love with powerful landlords.

Gentry: generally speaking, it refers to people who have been studying for generations since the Han Dynasty, studying Confucianism, such as Wei's father and son, Jingfang and Zheng Xuan.

Gate valve: it is biased towards aristocratic families in the Jin and Southern and Northern Dynasties, with strict hierarchy, which is the variation of the gentry since the Eastern Han Dynasty and the Three Kingdoms.

Aristocratic family: it is a combination of geographical relations and political terms, that is, the village is the most popular name, and the DPRK is the official.

Gentry:

Also known as family status, clothing, clan, power clan, aristocratic family, giant room, gate valve, etc. Door valve, a combination of family status and valve reading, refers to a noble family who has been an official for generations. The door valve system is the most remarkable system for selecting officials in China's history from the Han Dynasty to the Sui and Tang Dynasties. Its practical influence often leads to the monopoly of important official positions in the imperial court country by a few clans. The influence of personal background on his official career is far greater than his own talents and expertise.

it was not until the Tang dynasty that the gate system was gradually replaced by the imperial examination system based on the personal cultural level examination.
