Core Viewpoint - The article discusses the recent statement from the Ministry of Agriculture and Rural Affairs regarding the prevention of large-scale return of migrant workers to rural areas, emphasizing the need to promote employment rather than restrict movement [3][4]. Summary by Sections Current Employment Situation - There is pressure on migrant workers' employment due to macroeconomic fluctuations and a slowdown in urbanization, leading to reduced job opportunities in sectors like construction and urban infrastructure [4]. - The increase in surplus rural labor is driven by agricultural mechanization and a peak in college graduates, alongside industrial automation releasing new labor, which intensifies competition for jobs [4].

For instance, Chongqing and Shandong have initiated targeted training programs benefiting over 500 rural laborers, including nearly 400 from impoverished households [5]. - **Employment Services**: Improving employment services, particularly through the use of big data and cloud computing to create efficient job information platforms. An example is the employment assistance system in Xinyu City, Jiangxi, achieving over 98% support for returning workers [5]. - **Rural Employment Opportunities**: Shifting focus to explore local employment potential in rural areas, leveraging opportunities in sectors like specialty agricultural products, rural tourism, and education services. Successful cases include rural tourism in Anji, Henan's instrument manufacturing, and e-commerce in Suining [6]. Conclusion - The potential issue of large-scale return of migrant workers can be seen as an opportunity to promote urban-rural integration and rural revitalization. By preparing in advance and enhancing the skills of rural laborers, it is possible to alleviate urban employment pressure and stimulate local economic development [6].
