The factors that affect customers to choose the farmers’ market or supermarket are related to their shopping styles and age. While the young generation trusts the product of supermarkets, they are worried about the quality of food in farmer’s markets and demand to improve the shopping environment and food security. Especially in the old farmers’ market such as the subject of this survey (Shalong Market), however, various social-economic activities could be found because of the closer social relationship between customers and sellers there. From the results of the questionnaire and observation, people’s activities in the farmers’ market could be defined as “Exchange of Economic Information”, “Improvement of Life Quality”, “Medical and Educational Support”, “Cultural Activities”, “Support for Old Customers”, and “Health Maintenance”.
