There may be many reasons why Drunken Fairy Duck did not work for a long time. First of all, an unauthentic formula may result in unsatisfactory color, aroma and taste of the tea-oil duck, which will directly affect the customer's consumption experience, thus affecting the reputation and sales of Zuixian Duck. Secondly, unsatisfactory geographical location may also lead to poor business. For example, the location of the store is too remote or the transportation is inconvenient, which will cause the loss of many potential customers.

If Zuixianya Restaurant is not in business for a long time, you can consider improving these aspects. First of all, research and adjust the formula to ensure that the tea oil duck is more in line with consumers' tastes and needs. Secondly, choose a suitable geographical location, such as a commercial area with a large flow of people or near a residential area, so as to attract more potential customers. In addition, we can also improve the visibility and reputation of Zuixian Duck Restaurant by providing high-quality services and conducting publicity and promotion.
