Long dynasty group limited has been involved in the agro-processing industry since 1986 and was the first to be identified by eight national ministries, namely, the ministry of agriculture and the ministry of finance, as a priority national agricultural industrial company, and the export of food and agricultural products no-certificate enterprise. Long da has been awarded china's brand name with a great reputation, with its big fans and dragons' low-temperature meat products, dragons' hot and frozen meat, and then the chinese title, which has led to the formation of a powerful brand of three chinese brands, which has been designated "china's 500 most valuable brand". For more than three decades, the dragon group, based on the agro-industrialization of agriculture, has consistently pursued food security and a modern agriculture-oriented approach, has been promoting the accelerated conversion of new and old kinetic energy in the green food industry. It has completed a large-scale industrial cluster of more than 500 different types of exports (food, frozen vegetables, fd products, beans, water products, food oil products, meat products, etc.) across a wide range of food, chemical, mechanical, modern technology, packaging, etc. Businesses earned $5. 16 billion in business income in 2021, an increase of 18. 6 per cent over the same period; profits of $660 million, an increase of 13. 6 per cent over the same period; export earnings of $220 million, an increase of 6. 6 per cent over the same period; and taxes of $670 million, an increase of 52. 8 per cent over the same period. In more than 30 years of exploratory development, the dragon dynasty group has built a well-managed closed-ring food safety and security system through "source construction, strict control, full-scale testing, two-way warning, and back-to-back" in which companies' core competitiveness has been built, representing the country on several occasions, under official inspection by the ministry of health, labour and welfare of japan, which has served as an important benchmark for the official and client evaluation of chinese factories. The self-established testing centres, which have been certified by cma and cnas, have invested $80 million in 1067 indicators for precision detection of agricultural residues, physicochemicals, heavy metals, additives, microorganisms, allergies, transgenics, etc., which are always synchronized with japanese standards and cover the entire production and processing process. Establishment of a well-developed production regulatory database based on standards and norms such as ssop, gmp, haccp, and a system of food security throughout production, circulation and consumption. The leaders of modern agriculture start farming, grow farming. The first development of over 60,000 acres of self-controlled vegetable base throughout the country, through the introduction of order farming, which allows farmers to have planting plans throughout the year, together with a "cost-plus-profit guarantee" pricing formula, has made farmers' incomes more stable and has fundamentally addressed the ills of sharp market fluctuations in farmers' incomes. The introduction of more than 60 new varieties of vegetables from abroad each year, the permanent deployment of plant insurers to provide technical guidance, the increasing input and improvement of agricultural machinery, the technological, managerial and efficient upgrading of agricultural production and the significant improvement of the quality and cost competitiveness of chinese agricultural products. Through the whole-industry chain development model, more than 200,000 farmers have been effectively involved in processing, planting, transport and other services. This has contributed to the continuous integration of the 123rd sector and to the revitalization of the rural sector.

(c) actively apply big data and networking technologies to accelerate the process of enterprise intellectual production and increase the productivity of enterprises. At the same time, with the development of the internet+green foods, electrical platforms, such as the dragon cat flag and kyoto flag, have been enabled to keep the dragon brand alive. In cooperation with the beijing university of aeronautics and astronautics, a project to develop new materials, such as graphite and lithium batteries, has been set up and put into operation at the chinese test base in chinan innovation valley, and has entered into a rapid development phase of building core competitiveness with science, technology and innovation。
