Huai'an City has established a "four-in-one" promotion mechanism that has led to the development of 51 provincially recognized unique countryside projects, forming a model for sustainable development.

First, the city has implemented a dual-engine approach driven by industrial revitalization and brand empowerment. Leveraging the regional "Ancient Huai'an Flavor" brand, the city has nurtured clusters of specialty agricultural products such as Huai'an rice and Qingong meatballs, while its Dingji cucumbers have earned national geographical indication certification. Additionally, the city's innovative "agriculture plus" integration strategy has also spawned nearly 50 agri-tourism projects.

Second, the city is advancing long-term management in tandem with ecological restoration. For example, with the establishment of a "five-dimension" management system, Zhangzhuang Village in Hongze District has reclaimed 120 mu (8 hectare) of farmland through comprehensive land remediation and restored a 3.5-kilometer ecological corridor along the Caize River; Xinhua Community in Xuyi County established a "household classification–village collection–town transfer" system that has achieved a 50% reduction in waste.

Third, the city has deeply integrated a comprehensive co-governance system with rural civilization promotion measures. With the establishment of a governance model that blends village self-administration with social participation, Gangbei Village in Lianshui County pioneered a "three meetings and one agreement" system and created 1,500 square meters of cultural murals, effectively using village regulations to encourage the abandonment of outdated customs. Overall, the unique countryside projects have fostered over 3,000 model families, with simplified wedding and funeral practices adopted by more than 90% of residents.

Fourth, the city has made systematic efforts to promote institutional innovation and establish demonstration projects. It has set up a framework featuring top-level planning, clear responsibilities, collaborative efforts, and the use of both incentives and restraints. The framework helps drive rural revitalization through industrial advancement, generating replicable and scalable models for industrial development. Moreover, a dynamic update mechanism is also in place, facilitating the exploration of reforms in rural construction and management. At the same time, the city has been using an integrated media matrix to actively showcase these construction achievements, offering diverse examples of rural revitalization.
