In ancient times, people valued "expensive". That is, an official, an official of the civil service class. There is an old saying: learning to be excellent is an official. That is, the social status order of scholars, agriculture, industry and commerce.
However, there is no written provision for nobility, but it is described in expression, which is different from wealth.
To put it bluntly: being an official who only eats wages is honest and clean. No corruption, no bribery, no prestige, no economic strength.
What is the fortune? Cai Zheng is an honest official, don't you think? You may be partial to wealth, but wealth can be big or small.
