Chinese news reports have led to a lot of criticism and controversy， the main causes of which include the contradiction between different interests, the various conflicts between moral values, and the complexity of social environment and news events. People began to question the old system of moral belief. The old professional norms have lost control of the press. But the new press ethics system is far from established. These conditions, of course, lead to double chaos of news reports and social evaluation of the news media. Therefore, it is necessary to explore a reasonable media ethics system that can fit the reality and win public recognition. Such studies must be built on ethical analysis of realistic events, and also take the realistic problems and universality of the theory into consideration.  ″The case of killing children in Nanping″ is a case in point. Based on its reports, people raise some fundamental questions: why do regular news reports like the case mentioned prompt such severe controversy and criticism? If not reported, the media have lost the value of existence! If reported, it will endanger people's lives because of ″following-suit″ effect. Are the media loyal to professional mission or to people's lives? Are there any reliable ethical principles people can conform to?  Through the preliminary analysis, we believe that there is some loyalty chaos in the reports and the criticism of ″the case in Nanping.″ Therefore, according to the Chinese news reports tradition and the needs of social solidarity, we can consider the reconstruction of Loyalty Ethics. First of all, confirm the primary ethical value of loyalty. Second, choose the current primary loyalty principle. Third, confirm the specific objects of loyalty and rank them. But further analysis shows that the above three principles are not sufficient, We also need to think about how to ensure the correctness of loyalty. Therefore, we can put forward the last and the most important principle: Loyalty to Justice. It is the soul of Loyal Ethics, which brings the direction and openness for loyalty. What is justice? Rawls's ″Two Justice Principles″ provide the important inspiration and basis. Therefore, we argue that the public loyalty is the highest form of loyalty in the news reports, and the basic connotation of public loyalty is the loyalty to justice. Such loyalty principle provide the adequate moral guidance for ″the case in Nanping″ and the current news reports. Therefore, the reports with too much emotion and repetition are deviation to the dominant loyalty of media. News should be carefully reported on the basis of justice and realistic conditions so as to reduce the ″following-suit″ effect to the minimum. Loyalty to Justice can also facilitate the better treatment to the justice of the minority group, such as the murderer and direct victim. The realistic news environment is diverse. Therefore, the choice under it becomes difficult. But only on the basis of social justice can the reporter's loyalty and professional conduct be kept in the right direction. And the pursuit of justice is also the main responsibility and value of the news media during the period of social transformation.
