Whether in first - or second tier supermarkets or supermarkets in third - or fourth tier cities, the profit margin of children's playgrounds is very large. So, site selection is important. Although the rental cost of supermarkets is relatively high, it can bring more opportunities for success and make the profits of children's playgrounds better. Even if the rent is a bit expensive, it is still worth investing in. What is the appropriate size for the area? Operators can observe the surrounding situation, see how many residents there are around the supermarket, their purchasing power, the size and influence of the supermarket, and how many people come to visit the supermarket, etc. Then they can choose the appropriate area based on the actual situation. Generally, a children's playground in a supermarket can choose 200-300 square meters, while a large shopping mall is another matter.
