The “Guan Guangmei Series Reports” in 1987 triggered widespread discussions on whether China’s reform is capitalist or socialist. The essay found that the news practice of “Guan Guangmei Series Reports” displayed the process of self-reform of Chinese party newspapers in the 1980s through the examination of narratives by senior leaders of Economic Daily, personal memories of journalists and published texts. Firstly, the essay presented the journalist group’s three visits to Benxi. It was pointed that through a series of news practice, they experienced from a mixed “news culture” to the “Mass Line”. At the end of the visits, the group established rational and emotional relationship with local masses. Secondly, the essay examined Economic Daily’s publication of “Guan Guangmei Series Reports”. It was pointed that the newspaper office adopted the strategies of “observe changes” and “take the initiative” to enable masses to fully participate in expressing their opinions. During the process, the discussions and editorials reached a consensus gradually, which highlighted the characteristic of People-centeredness of Party consciousness in the “Mass Line”. At last, it was pointed that the previous understandings of this news practice had limitations of teleology, which reflected the bias in the writing of 1980s’ Journalism History. Therefore, if we would like to establish Chinese characteristic journalism, exploring traditional Party Newspaper Theory by a “maintaining subjectivity” approach should be taken into consideration.
