Deeply Cultivating the Local Market and Empowering Cross-Border Business  

The Group has always focused on building materials as its core business. Centered on the local industrial foundation of the parent company, it has established two core business segments: 'Domestic Building Materials Sales and Engineering Support' and 'Cross-Border Import and Export Trade of Building Materials.' These two segments support each other and develop collaboratively, forming a business pattern of 'local business solidifying the development foundation, cross-border business opening up growth space,' thereby realizing the release of the Group’s industrial value.  
3.1 Local Core Business: Building Materials Sales and Engineering Support Services  
As the foundational business of the Group, operated primarily by the parent company Guangzhou Lansha New Building Materials Co., Ltd., it deeply cultivates the domestic building materials market, focusing on material supply demands for core scenarios such as engineering construction and project implementation, providing standardized, high-quality, one-stop building materials sales and engineering support services, which serve as the core support for the Group's sustained development.  
· Supply Chain Integration: Establish a strict supplier selection and management system, integrate high-quality building materials resources, ensure stable product quality and timely delivery, and meet the material procurement needs of various engineering projects;  
· Customized Supply: Provide personalized supply solutions tailored to the project needs of different customers, covering the entire process including material selection, quantity matching, and on-time delivery, adapting to the diverse requirements of construction projects;  
· Standardized Services: Build a standardized service system from order coordination, supply and delivery, document support to after-sales follow-up, providing compliance documents such as product quality certificates and factory inspection reports with the goods, ensuring smooth and compliant procurement processes for customers.  
With stable product quality, efficient supply capabilities, and a professional service system, the parent company has established engineering material supply cooperation with multiple enterprises including Guangzhou Eastern Engineering Co., Ltd. and Guangzhou Mingfeng Agricultural Development Co., Ltd., completing multiple batches of building material supply and forming a good cooperative reputation in the local market.

3.2 Strategic Incremental Business: Cross-Border Import and Export Trade of Building Materials
With the parent company as the central coordinator, linking the Hong Kong cross-border hub and overseas entities in Canada and the United States, a complete cross-border trade system for building materials is established, characterized by 'domestic demand connection, overseas resource integration, and professional cross-border operation.' This is the core incremental segment for the group's future development and the key focus of the group's global layout.
· Core Logic: Relying on the parent company's mature domestic market and supply chain resources, combined with the abundant building materials resources, advanced manufacturing processes, and strict quality standards in North America, integrate high-quality overseas building materials into the domestic market. At the same time, leveraging the channel advantages of overseas entities, promote high-quality domestic building materials to the North American market, achieving a mutual exchange of resources and bidirectional empowerment in the building materials industry domestically and abroad;
· Operating Model: The parent company oversees domestic customer demand, supply chain support, and overall cross-border trade management. Hong Kong-related enterprises provide professional services such as cross-border transshipment, compliance implementation, and foreign exchange settlement. Overseas entities in Canada and the United States are responsible for local resource integration, channel connection, supplier cooperation, and local operations management, forming an efficiently connected, compliant, and closed-loop cross-border trade system;
· Business Advantages: Leveraging the group's domestic industry foundation and overseas compliance layout, achieve precise matching between 'high-quality overseas resources' and 'domestic market demand.' Meanwhile, with standardized cross-border operation processes and a professional operation team, ensure cross-border trade is compliant, efficient, and stable, opening up new growth opportunities for the group's development.
