Since the Chinese Communist Party (CCP) leader Xi Jinping took over the power from November 2012 to date, he has already shaped a specific outline for guiding, developing and practicing the political work of People's Liberation Army (PLA), which can be used for exploratory case studies. Therefore, I'd like to go through the process of exploring the literature to summarize and analyze the characteristics and effects of the political work of PLA at this stage, in order to develop observable indicators for the purpose of understanding the enemy's situation. Accordingly, I induce the characteristics and impacts as follows: to enrich the connotation of service assurances for the political work of PLA, to provide political guarantee, spiritual mobilization and personnel recruitment; to strengthen the legitimacy and irreplaceable nature of obeying the command of the party, which makes the PLA the tool for dictatorship; At this stage, the political work of PLA focuses on the "real combat" dimension, which is its primary task; to expand influence and capability of the "three war" for real combat; to deepen the function of political work for military operations other than war, in order to develop "lifeline" effect. Based on the above, I investigate the observable indicator for follow-up studies: recognizing the goal of strong army and the connotation of political work service assurance are keeping pace with times. The PLA uses the concept of "real combat" to eliminate difficulties of carrying on political work. To understand that PLA tries to expand the "three wars" capability, set the foundation in peacetime and wish it can bear fruit in wartime, in order to seize the right of interpretation and to influence the mental reaction of the audience. In addition, during the military operations other than war, the political work of the PLA plays a role as the bridge of military strength multiplier. In other words, the features, influence and index of the PLA political work mentioned above are based on description, explanation, induction and analysis, and all the connotation and indicators provided are references for future research.
