Shen Jinghong, a palace fighting champion, transformed into a modern gangster. When the police checked her household registration, she showed her jade pendant and said, "I am the noble concubine Chen." In order to apply for an identity card, she conquered the police station cafeteria with royal cooking techniques, outsmarted night market gangsters with palace rules, and became a star mediator relying on the wisdom of the palace. When the jade pendant is fully charged, she must make a choice between returning to the palace to be a canary or staying as a free man - and the way film policeman Li Xuan looks at her has already changed from suspicion to protection.
