The Ancient Chinese society was divided on the basis of Feudal System. This gave rise to social hierarchy of Ancient China by classifying the Chinese people into four social classes:
The lowest class in the ancient Chinese society were Merchants and Traders, they were not considered as respectable people.
Then the second to lowest were the Craftsmen, they were regarded as labours, and also were not given respects and privileges.
Then it comes the Peasant Farmers. They were considered as a higher class compare to the Merchants and Craftsmen, since they work in the farm and provide food, and since agriculture in China was a key element of the entire civilisation.
The second to highest were the scholars, they were considered as the low level aristocratic lineage in the ancient Chinese society.
Finally it comes the highest social class, the King. The King and his family were placed on the top level of the ancient Chinese social pyramid, they were the most respected people and they ruled the people in the entire country.
Apart from them, Soldiers were also very respected, they were the second most respectable people in ancient Chinese society.
Hoped this helped!
