"Jinkou Yuyan" (Golden Mouth and Jade Words) originates from the Book of Jin. Its original meaning refers to the words spoken by emperors, as ancient emperors were regarded as the Son of Heaven, and their words carried supreme authority, as precious and unalterable as gold and jade. Later, this idiom came to generally mean that one's words are counted and carry tremendous weight, describing a person who keeps promises and never goes back on their word. In its deeper meaning, it emphasizes the combination of integrity and authority, reflecting both the noble status or high character of the speaker and the absolute trust of the listener in their words. It is mostly used in formal occasions, such as praising a leader, elder, or authority figure for their reliable promises, and can also be used among friends to tease someone whose words carry great weight. In terms of cultural background, it reflects the high regard for "trustworthiness" in traditional Chinese culture, especially the ethical concept that "a ruler never speaks in jest." Its emotional tone is positive, carrying a sense of respect and admiration, though when applied to ordinary people, it can sometimes carry a slightly exaggerated or humorous nuance.
