Abstract: Popularization of the Marxism is the process of its affecting people. The effect of dissemination influences how much the Marxism can be popularized. However, there are disadvantages to affect the dissemination of popularizing Marxism, they exist not only in choice of the content and way of dissemination, but also in identity of people sentiment. In order to get out of the trouble, popularizing Marxism must be changed from making the content to be close to people, varying the way of dissemination and fusing the main values, and renewing the Red Song meets this need exactly.
