Truth in journalism, which is also called “objective truth”, meets challenges from practice, value and context requirements. It is difficult to conquer these challenges in the traditional way like breaking through distinguishing phenomenon and essence, macrography and microcosm, extension and intension, proof and judgment, report and understanding, instant and infinity etc. In this article, it takes semeiology as the theoretical basis to analyze the semeiotic process of producing, spreading and receiving news. Then it concludes that the truth is the semeiotic truth instead of objective truth. The semeiotic truth exists in the interactive process of finding the harmony in fact recognition, explanation and aesthetic. And this means the essence of seeking truth in journalism lies on finding out the semiotic signs which are objective, valuable and resonant. That indicates the semiotic orientation for truth in journalism.
