The “Access to Vocational Chinese” Series is a series of vocational Chinese language textbooks jointly developed by the Center for Language Education and Cooperation of the Ministry of Education and the Talent Center of the Nonferrous Metals Industry. Based on the actual teaching development needs of “Chinese + Vocational Skills” in various countries and relying on Chinese vocational colleges, experts from various fields have been organized to participate in the development. Referencing the Chinese Proficiency Grading Standards for International Chinese Language Education and the Chinese Proficiency Standards for Vocational Education, the textbooks are divided into three levels: elementary, intermediate, and advanced. Each level follows the compilation concepts of “integration of language and skills” and “easy to learn, convenient to teach, and practical to use”. According to the typical work scenarios, work tasks, and frequently used expressions in relevant occupations, sections such as texts, conversations, language points, and exercises are designed to continuously improve learners’ Chinese application proficiency and key technical abilities in the field of vocational technology, providing assistance for learners to quickly get familiar with and adapt to the work environment.
