The scientificity and truthfulness of Marxist theory are crucial aspects of our research. To gain a comprehensive understanding, it is essential to examine Marxism within a reference frame and comparative perspective. In this regard, exploring Marx's critique of Proudhonism becomes significant, as it provides insights into the ideological transformations he achieved. Proudhonism, a small bourgeoisie socialism and anarchism that emerged in France in the 1840s and spread across Western Europe in the 1850s-1860s, had intricate connections with Marxism. This analysis not only broadens our research horizon but also holds practical implications for today's society. Thus, our research holds both theoretical and practical significance.

With the development of college education and the increasing demand of students' comprehensive quality training, the second classroom in colleges and universities has attracted much attention as an important form of education. The purpose of this study is to investigate and analyze the development of the second classroom in colleges and universities, and put forward corresponding countermeasures and suggestions. Through mixed research methods, including questionnaire survey, interview and literature research, we have a comprehensive understanding of the type and quantity of college second classroom projects, student participation, project quality and effectiveness, and organization and management. On this basis, we put forward a series of targeted countermeasures and suggestions, including strategies and measures to improve student participation, suggestions to improve the quality and effect of the project, and optimize the program of organization and management. The results of this study have important theoretical and practical significance for universities to improve the level of the second classroom and promote the all-round development of students.

With the progress of the times, the development of information technologies such as big data, artificial intelligence, and cloud computing is also in full swing. These new information technologies continue to impact China's existing traditional industries, enabling them to integrate and innovate, while also promoting China's entry into the digital economy era. For the accounting industry, this has also led to higher demands from society for accounting professionals, and most basic accounting personnel will face the dilemma of job changes as a result. This requires vocational colleges to consider more comprehensive training strategies when cultivating accounting professionals, so that accounting professionals can adapt to the new accounting functional requirements of contemporary society.

The "chain length system" is a breakthrough attempt made to adapt to the needs of industrial management under the new development pattern of dual circulation and its industrial policy form. The cultivation of cross-border e-commerce talents in vocational colleges has received much attention. Currently, there are still many problems in the construction and teaching mode of cross-border e-commerce courses in vocational colleges, which are highlighted as the disconnection between course offerings and industry needs, low practical value of course content, low professional literacy of graduates, and inability of graduates to handle practical work. Therefore, it is crucial to construct and innovate a golden course for the development of cross-border e-commerce careers in the new era, focus on strengthening and supplementing the cross-border e-commerce talent chain, and open up the "last mile" of the cross-border e-commerce talent chain, so as to  improve the specifications and quality of talent cultivation. Starting from the pain points and difficulties of industry enterprise demand, curriculum teaching patterns, characteristics, and main contradictions as breakthrough points, we will carry out the construction of golden courses, using "task driven", "module teaching", "project teaching", "project incubation", "achievement recognition", and "point exchange" throughout the entire teaching process, in order to enhance the core competitiveness of cross-border e-commerce talents and serve the chain leader system in the Guangdong Hong Kong Macao Greater Bay Area.

The implementation of the "the Belt and Road" requires the common development of the "five links" of policies, facilities, trade, finance and popular support, among which "people to people connectivity" is the premise of the coordinated promotion of the "five links", and cultural communication, exchange and cooperation are the foundation and guarantee of the popular support project. The "the Belt and Road" cultural communication, exchange and cooperation are diverse in content and form. We need to identify the opportunities and challenges we face, make long-term strategic plans, and take practical countermeasures and implementation paths according to the characteristics of cultural communication diversity. Some domestic scholars have conducted research on cultural communication strategies and analyzed the opportunities and challenges they face, but there is a lack of diversity analysis on the forms of communication that should be adopted. This paper explores and studies the "the Belt and Road" cultural communication strategy, implementation path and safeguard measures, constructs a new model of diversified cultural communication and exchange cooperation, and tries to play a certain role in promoting the actual effect of cultural communication and exchange cooperation and better safeguarding the "the Belt and Road" community of interests.
