What is the relationship between Confucianism and China's so-called traditional culture? How to define Confucianism accurately?

If traditional culture is a dish, Confucianism is one of the ingredients.

Thought is spiritual, but the word Confucianism does not simply refer to the thought of the spiritual world, it also includes the influence of Confucianism on the social system. Governing the country always needs a theoretical basis. Of course, you can sell dog meat by hanging sheep's head. Confucianism is a signboard, and what to sell is decided by the shopkeeper.

Not to mention the content of social system, spiritual thought alone can only give a general definition. Thought is the product of the human brain. I don't know how many people have processed Confucianism for thousands of years, and may finally remember some "everyone", but are these "everyone" thoughts considered Confucianism? So what counts and what doesn't count adds a lot of fun to future generations after dinner.

The meaning of thought lies in enlightenment. It is enough for you to find something that inspires you and establish your own complete ideological system. The popularity of statistics has shown that "precise definition" is just a pursuit. Please add a "confidence interval" before each definition.
