气节 (qì jié) is a classical Chinese noun expressing unwavering moral integrity — the inner strength to uphold ethical principles, especially in the face of pressure, temptation, or adversity. Literally, 气 (qì) refers to one’s vital spirit or moral energy, while 节 (jié) means ‘integrity,’ ‘restraint,’ or ‘moral boundary’ — together, they evoke the idea of a person’s spiritual backbone and steadfast virtue.

This term carries strong Confucian and traditional cultural weight and is often used to praise historical figures, scholars, or ordinary people who refuse to compromise their values, even at personal cost. It appears frequently in literature, speeches about national character, and discussions of ethics and leadership. Though formal and somewhat literary, it remains widely understood and respected in modern Chinese discourse, particularly when emphasizing courage, honesty, and principled conduct.
