The book "Qiao Family Business Wisdom" is worth a read.

They say wealth brings desires, but the Qiao family managed this exceptionally well—they truly had their system down:

1. Rules come first: The Qiao family didn't rely on descendants' self-discipline but on strict institutional rules. Violations resulted in immediate loss of inheritance rights or expulsion from the home.

2. Leaders lead by example: Qiao Zhiyong, a key figure in the family, strictly adhered to family rules even at the peak of his wealth—taking no concubines and avoiding extravagance, setting a high moral benchmark for future generations.

3. A family culture of "cultivating virtue through business": The Qiao family viewed wealth as a "social responsibility" rather than a tool for pleasure. During famines, they opened granaries to distribute grain, channeling excess resources into altruistic charity.
