Explain how to understand traditional culture with dialectical negation.

Dialectical negation is the negation of the thing itself, the link of its development and the link of its connection.

Methodology: We are required to establish a sense of innovation, to be both bookish and practical, and to respect books and authority. We should base ourselves on practice, emancipate our minds, seek truth from facts, keep pace with the times, and constantly realize the innovative development of theory and practice.

Combining with reality: in the face of traditional culture, we should take its essence, discard its dross, bring forth the new, critically inherit, make the past serve the present, absorb beneficial foreign cultures, face the world, learn from others, oppose "conservatism" and "closedness", oppose "national nihilism" and "historical nihilism", base ourselves on social practice and give full play to the fundamental interests of the people.
