Building decoration industry is a traditional labour-intensive industry, the quality of the project is highly dependent on the level of individual operations of industrial workers, so the quality of the project is prone to vary, the problem of project homogeneity has become a prominent problem that has long plagued the development of the industry. To fundamentally solve this problem, it is necessary to change the traditional mode of production through thorough technological innovation, the injection of new development factors, to achieve intensive development, we must establish science and technology as the guide, design and factory production as the support of the industrial development model, the uncertainty of the "rubbermaid" type of production into a high degree of certainty "building blocks". The uncertainty of the "Play-Doh" type of production into a high degree of certainty of the "building blocks" type of production.

Since 2022, Donghui Lianyi has been devoted to research and development of "new green building materials + new assembly technology", through standardised design, industrialised production, assembly construction and information technology synergy, and solved the industry's most difficult homogenisation problem with subversive assembly technology breakthroughs, and innovated the traditional decoration of "dragging mud and water". The backward technology of "dragging mud and water" has revolutionised the traditional decorative "backward process", given the construction industry manufacturing attributes for the first time, broken the status quo of the construction industry that relies on the level of individual work of industrial workers, and achieved high-quality project delivery with a quality deviation rate of no more than 1%, which has won the recognition of customers.

The new technology and new materials have brought great green low-carbon social and economic benefits. The construction industry is a major carbon emitter, and at the same time, it is the "people's aspiration for a better life", so the green transformation of the industry is imperative, and there are also huge opportunities for development. Through continuous R&D and application of new technologies and materials, ASEA has obtained nearly 8,000 patents. With the technical feature of 100% recyclability to achieve comprehensive carbon reduction of more than 50%, formaldehyde and TVOC release is better than the highest international environmental protection level by more than 4 times, which solves the industry's most prominent environmental pollution and people's most concerned about air health issues. Through 100% factory manufacturing, 100% assembly and installation, and 100% dry construction, the project duration has been shortened by more than 50%, and on-site losses have been reduced by more than 70%, achieving significant improvement in efficiency and substantial savings in resources. As the concepts of green development and green life continue to take root in people's minds, assembly interior decoration with new technology and new materials as its core has won wide recognition in the market and among customers, and has grown to be an important growth point of performance for Yasha, and has played a positive role in promoting changes in the industry, the enhancement of the ecological quality of urban habitats, and the sustainable development of the society.
