Why was there no social mobility for the Chinese people?

Historically, China was structured around a rigid social hierarchy that limited opportunities for social mobility. The system was based on Confucian principles that emphasized maintaining societal order and stability, which often reinforced the privileges of the elite classes and restricted upward mobility for the majority of the population. Additionally, factors such as family background, education, and connections played a significant role in determining an individual's social status and opportunities for advancement.
