Future Development: The group aims to leverage next-generation technologies such as 5G, the Internet, and artificial intelligence to establish an industry resource-sharing service platform. It will promote shared factories, service-oriented manufacturing, and supply chain resource sharing with extensive coverage across China and strategic expansion in "Belt and Road" countries. The goal is to achieve the "Double Hundred" target within 3-5 years: 100 shared duct factories in China and 100 in "Belt and Road" countries, ensuring a "Duct Brothers" shared factory every 300 kilometers in China. The group will adhere to a strategy combining physical development with capital-supported expansion, continuously increasing scale and capacity, aiming for an IPO listing within 3-5 years. It will implement strategies for innovation-driven growth, quality enhancement, technology empowerment, and high-end brand cultivation to promote high-quality development, enhance brand core value and competitiveness, and establish Zhongwei's "Duct Brothers" as a nationally and internationally recognized brand. The ultimate goal is to become the leading integrated supplier and service provider of ventilation system ducts in China and globally.
