Abstract: The current academic cognitive interpretation of political discourses is confined to subjective and abstract theoretical illustration，ignoring the objective as well as scientific empirical argument support. The political discourse of the speech of Chinese President Xi Jinping，which was delivered at the Commemoration of the 70th Anniversary of the Victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti- Fascist War，bears far- reaching insight and tremendous ignificance. Based on the English version of the speech offered by the website of the Ministry of Foreign Affairs of PRC，this paper，through the perspective of cognitive metaphor，uses the Wmatrix system，which has a powerful metaphor analytic function，and interprets in depth the process and pattern that the speech’s topic words of high significance and its semantic field build up the cognitive metaphors. The paper finds that the metaphor form constructed by the high- significance nouns，verbs，and adjectives and the metaphor form’s meaning constructed by the semantic field tally with one other.

Key words: political discourse, ideology, cognitive interpretation, cognitive metaphor, Xi Jinping, speech
