1. Social role expectations: In traditional beliefs, men are often expected to play strong, brave, and capable roles. Saying 'no' may be seen as a sign of weakness and incompetence, which does not meet the general expectations of society for men.
2. Sense of responsibility and pressure: Men are usually endowed with more sense of responsibility, whether in the family or workplace. When facing challenges and difficulties, they may feel greater pressure to prove that they are capable, so they are unwilling to say 'no' easily.
3. Self identification and self-esteem: Men's self-identity and self-esteem are often closely related to their abilities and achievements. Saying 'no' may damage their self-image and lower their self-esteem, so they are more inclined to show confidence and ability, and try not to say 'no' even when facing difficulties.
