Answer:
✔️Allowed families to gain financial gains.
Step-by-step explanation:
The reason that is NOT a reason for China to adopt the teachings of Confucius is "allowed families to gain financial gains"
Confucianism as used in China is considered a worldview, a political ideology, a social ethic, a scholarly tradition and a way of life. Confucius actually emphasized relationship between parents and children. Confucius discovered the human relationships that will help bring peace. The ethical values of Confucius has served as the source of inspiration for over 2,000 years.
Actually, China will adopt Confucius teachings due its promotion of moral values, peace, happiness and family relationships. Families having financial gains is not a reason for going with Confucius.
