The word 尽情 is formed by combining the character 尽, meaning "to exhaust" or "to use to the fullest", with the character 情, meaning "feeling" or "emotion". Together, they create a conceptual fusion where the first character acts upon the second, producing the integrated meaning of "to one's heart's content" or "as much as one wishes", essentially conveying the idea of giving full rein to one's feelings or desires without restraint.
