On the morning of September 7th, Secretary Ma Zhenshan of the International College of Central South University of Forestry and Technology and his team of leaders and professional teachers visited Wontech for inspection and exchanges, to discuss the academic and practical exchange mechanism of international trade, and to explore more possibilities for cultivating more international talents. Rex, International Marketing Director of Toolstar Group, Chen Lixin, Minister of Human Resources and other company leaders attended the exchange meeting. Central South University of Forestry and Technology stated that the school has a high academic level in international trade theory, but it is relatively lacking in actual combat experience. There is uncertainty as to whether high-level academic papers have the ability to guide actual combat, and with Wontech’s success in international trade The exchange of experience can make up for this shortcoming. Wontech said that although the company has accumulated rich practical experience in international trade, it lacks systematic theoretical guidance. This has created obstacles to the training of talents, especially management-oriented international trade talents, and exchanges and cooperation with schools will greatly solve this problem. The two sides also conducted in-depth exchanges on issues such as international trade talent training, school-enterprise production-research cooperation and other issues, and discussed the follow-up specific cooperation.
