With the development of social media,there have been new changes in the characteristics and ways of college students to express their emotions under the influence of technological empowerment,which also provides a new perspective for the research of college students'patriotic education.Based on the theory of emotional com-munication,it is found that there exist realistic difficulties in emotion awakening,emotion sharing,emotion reso-nance and emotion relief in college students'patriotic education.Therefore,it is necessary for colleges and univer-sities to speed up the construction of a four-dimension education system of"knowing,loving,believing and act-ing":with"knowing"as the basis,grasp patriotic cognition in emotion awakening;with"loving"as the band,cultivate deep patriotic sentiment in emotion sharing;with"believing"as the guidance,strengthen the ambition of a powerful motherland in emotion resonance,and with"action"as the foundation,practice serving the country in emotion relief.These four links conduct and interact with each other,and constantly affect the effectiveness of patriotic education.
