1 Introduction

The development background of the "Chinese+Vocational Skills" project was introduced, emphasizing the support and encouragement of Vice Premier Sun Chunlan of the State Council for the project. With the promotion of the "the Belt and Road" initiative, the project has attracted more attention. The article takes "Chinese+Engineering" as the research object, analyzing the connotation, current situation, challenges, and countermeasures of engineering Chinese.

The concept and content of "Engineering Chinese"

Introduced the concept and content of "Engineering Chinese". Li Quan classified "engineering Chinese" as a subcategory of business Chinese, Zhang Li defined specialized language teaching, and Li Yi classified the specialized Chinese teaching system. Engineering Chinese is a product of the integration of Chinese language and vocational skills, and is a small branch of specialized Chinese language that serves international engineering construction cooperation between China and foreign countries. The learners are mainly non-native Chinese language engineering builders. Engineering Chinese language teaching needs to combine professional knowledge in the engineering field with Chinese language learning, in order to meet the needs of non-native Chinese speaking engineers, technicians, and related practitioners to use Chinese for professional communication in engineering project planning, design, construction, management, and technical exchanges. The core content includes basic professional vocabulary and terminology in the field of engineering, general technical specifications and standards, and relevant content of engineering project management.

Practical experience of "Chinese+Engineering"

Under the framework of the "the Belt and Road", China's vocational education cooperates with the co construction countries to promote the development of "Chinese+vocational skills" education. The China Thailand Railway Cooperation Project has promoted the cultivation of railway technical talents in Thailand. The Confucius Institute at Kongjing University has cooperated with Wuhan Railway Vocational and Technical College to cultivate more than 200 composite technical talents. The Laos railway project has helped cultivate technical backbone and experts, filling the gap in railway vocational education. The "Chinese+Machinery" course in Ethiopia has trained mechanical operators who understand Chinese and improved the communication efficiency of Chinese funded enterprises. The "Chinese+Welding Technology" training course in Pakistan has trained urgently needed versatile talents. Elevator companies are facing a shortage of local talents when going global. Hangzhou Vocational and Technical College in Zhejiang Province has launched a "Chinese+Elevator Engineering Technology" training program to address language communication and professional competence issues. Special courses such as "Chinese+Aviation" and "Chinese+Robotics Technology" in countries such as Japan and Ukraine are popular.

Current Status and Prospects of Teaching and Research on "Engineering Chinese"

Analyzed the current situation and future prospects of research on teaching "Engineering Chinese". In terms of teaching resources, the development of engineering Chinese textbooks is relatively late, with limited quantity and types. Railway Chinese textbooks account for a large proportion, while textbooks in other fields urgently need to be developed. Among the newly added international Chinese textbooks in 2022, "Chinese+vocational skills" textbooks account for only 6.5%, mainly focusing on business and medicine, with few engineering related textbooks. But in recent years, the publication of the "Industrial Chinese" series of textbooks has provided new resources for engineering Chinese teaching. In terms of teaching standards, although some teaching standards have been released in the international Chinese education field, the teaching standards for "Chinese+" related majors or professions still need to be established. The release of the "Professional Chinese Proficiency Level Standards" and "Professional Chinese Teaching Syllabus" provides reference for vocational Chinese education. In terms of teaching staff, specialized Chinese language teachers need to possess cross disciplinary knowledge and professional teaching abilities. Currently, the construction of the teaching staff urgently needs to be strengthened. In terms of equipment, engineering teaching requires diverse and specialized training venues and facilities, and the application of virtual simulation technology is expected to alleviate equipment pressure. The construction of future engineering Chinese teaching resources needs to expand into specific fields, differentiate teaching implementation scenarios, provide advanced training for teaching objects, and strengthen the construction of teaching staff and practical training facilities and equipment.

5 Conclusion

In the context of "Chinese+" education, engineering Chinese, as an important component, plays a crucial role in expanding the workplace space for learners. However, as an emerging field, Engineering Chinese is still in the exploratory stage and requires the attention of experts and scholars to expand its branch scope, strengthen the construction of teaching resources, formulate teaching standards, improve teacher quality, and improve facility conditions, in order to promote the sustainable development of Engineering Chinese and "Chinese+" education.
