The stall economy emerged during the economic downturn, promoting urban consumption and employment, and injecting new vitality into the city’s recovery. With the normal operation of the economy, the unorganized, spontaneous, and gregarious stalls have gradually been marginalized by the city, driven away and constantly relocated. However, stalls are still one of the ways for the middle-aged and high-aged people to find employment. At the same time, the business of stalls depends on scale and crowds, which has also become the reason for a small number of people to gather. This project selects corresponding scenes and locations for this type of people by collecting different sounds from the streets, providing possibilities for the survival of stalls. At the same time, I pay attention to the damage of stalls to the urban environment. When providing a place to live, I also give the concept of environmental protection to reduce the possibility of being driven away and marginalized, and explore the possibility of the future existence of stalls.
