Recently, IEEPA organized a research team composed of well-known experts in the field of environmental protection to go to Hejin City, Shanxi Province for several days of on-site surveys and in-depth discussions on environmental protection work. The purpose of this survey is to comprehensively understand the current situation and challenges of environmental protection work in Hejin City, and provide strong support for the association's subsequent environmental protection projects and cooperation in the region. During the investigation, the expert group went deep into several key areas of Hejin City to conduct on-the-spot investigations. Experts not only paid attention to Hejin's remarkable achievements in environmental protection, but also keenly captured the weak links and potential problems in the current work. During the investigation, the leaders of Hejin City attached great importance to and actively cooperated. They not only personally accompanied the expert group to conduct on-site reconnaissance, but also organized a symposium to have in-depth exchanges with the expert group on the current situation, future planning, difficulties and challenges of environmental protection work in Hejin City. The pragmatic and sincere work style of Hejin leaders left a deep impression on the experts. They said that they would listen carefully to the opinions and suggestions of the experts, further intensify environmental protection work, and promote the continuous improvement of Hejin's ecological environment quality. Through this survey, IEEPA has a more comprehensive and in-depth understanding of Hejin's environmental protection work. The association stated that it will make full use of its professional advantages and resources in the field of environmental protection, actively provide technical support, project cooperation and personnel training to Hejin City, and jointly promote the environmental protection cause of Hejin City and even the entire Shanxi Province to a new level.
