The field of journalism often requires objective description, not subjective interpretation. One group of experts concludes that the view of any journalist is easily subject to a series of factors in the news production process, such as his values and beliefs, professional training, educational background, and the relevant factors alike. Nevertheless, the other group of scholars asserts that the objectivity can be completed, only when the journalists are willing to maintain a fair and unbiased reportage. Accordingly, just as the lighthouse in the ocean or the polar star in the sky, the objectivity of journalism serves as a guiding force for the boats to launch a correct and smooth sailing.
