誓死不二 is a Chinese idiom (chengyu) meaning “to swear to remain unswerving in one's loyalty or conviction until death; to be absolutely steadfast and faithful”. Literally, “Swear to die, without a second loyalty”.
During the Spring and Autumn period, Li Li, an official in charge of prisons in the State of Jin, was known for his integrity and impartiality in handling cases. He strictly adhered to the law in all judgments and sentences, treating high-ranking officials and common people equally, ensuring that laws were followed and crimes punished.
He discovered a wrongful death sentence and, believing himself responsible, ordered his subordinates to bind him and bring him before Duke Wen of Jin. Duke Wen wished to release him, but Li Li asserted that he must be sworn to uphold the law until death, demonstrating unwavering commitment.
