It is commonly believed that the current Chinese president, Xi Jinping, shares a leadership style with Mao Zedong on account of his charisma, prosecution of political enemies, and centralization of power. But is there any substantial evidence to supporting that belief? This paper seeks to answer the question by employing the Big Five model to investigate three dimensions related to leadership stylenamely, charisma, political tolerance, and need for achievement. The psycholinguistic program LIWC (Linguistic Inquiry and Word Count) is used to analyze Mao and XI's utterances in order to measure and compare their personal traits. Findings suggest that Mao and Xi share similar levels of extraversion' and openness to experience', but differ in conscientiousness', agreeableness', and neuroticism'. Thus, while both Mao and Xi exude charisma, Mao manifests lower political tolerance whereas Xi has a greater need for achievement.
