What chain convenience stores are the most in Haikou?

I am a local salesman in Haikou, and I know a lot about convenience stores in Haikou. The main brands of convenience stores in Haikou are Yikeyi, Yikeyi, Meiyijia, Yikeyi, k5 and Changyi. Yikeyi is an old local brand in Haikou with a history of 5-6 years, but the operation management team has been tepid and has not developed new stores in recent years, which is basically at a standstill. Meiyijia is the owner of a convenience store, but coming to Hainan seems unaccustomed. Opening a shop is mainly self-operated, and there are not many franchise stores. The operation of single stores is not very optimistic. Personally, I understand that the consumption level of ordinary people in Hainan still can't keep up with the level of Meiyijia. There are about 20-30 stores in Yizhijia, which mainly operate in the mode of fresh supermarket. At present, the number of stores is declining, and it seems that they have withdrawn from the Hainan market. K5 is poorly decorated and poorly serviced, and belongs to an unmanned state, so the market is basically difficult to see. At present, the development is relatively smooth, the number of stores is close to 300, the decoration is beautiful, and the commodity prices are relatively close to the people. Changyi has no distribution and management. At present, there are about 40 companies, which have no corporate nature and basically only provide decoration suggestions.
