1. Media's public opinion orientation and self-doubt: Over-analysis and self-doubt of marriage by the media will make people who want to get married feel resistant.

2. Cognitive error: I think marriage is the grave of love, which leads to anxiety before marriage.

3. The inadaptability of role transformation: establishing family consciousness and social responsibility independently will put pressure on the original relaxed shoulders and cause fear and anxiety about the uncertainty of the future.

4. Dissatisfaction with the marriage partner: I can't stand each other's shortcomings, which leads to fear of marriage life.
