Since its inception in 1995, dennis's day-to-day convenience store, which is part of a retail business group that combines the collection of department goods, mall, shopping malls and convenience stores, has continued to develop, with its own logistics centres, food processing centres, and private meetings, to form a large network of sales, mainly in zhengzhou, and to expand its markets to the provinces of hebei, shanxi, shaanxi, hubei, shandong, jiangsu and anhui. The dennis convenience store introduced a new type of retailing, encompassing retail stores, specialized stores, department stores, supermarkets, malls, wholesales, warehouses, etc. The zhengzhou business model was enriched by the introduction of knowhow (business technology) in advanced mall management. The dynamic industry has led to a diversification of business practices, competing with each other, learning from each other and enabling business behaviour to produce results that are relatively easy to obtain. The dennis refinery was formally established in 1995 as the next retail business group of taiwan's dong-yu group, which combines department stores, malls, convenience stores and logistics centres, as well as one of the two selected businesses nationwide, and was successfully opened with the strong assistance of provincial and municipal leaders. In 2002, dennis moved into china's retail chain, number 72 and number 24, with the country's largest retail company, number 79, in 2003. The company was awarded honors such as the “excellent foreign investment enterprise” in henan province, the “advanced unit for the integrated benefits of foreign investment enterprises” in zhengzhou city, the “ethical code of access to thousands of stores, the model for the purposes of service,” the “consumer trusts in the business market”, the “unfaltered advanced unit of 100 million shops” and the “significant contribution award for non-public enterprises”。
