1. Traffic congestion: As a large residential area, the traffic around Nanjing River and the city will be congested, especially during rush hours. This causes residents to face traffic delays and congestion when commuting or going out.
2. Noise problem: Because Nanjing Hecheng is located in the urban area, there are some commercial facilities, traffic facilities or other noise sources around it, which will have a certain impact on the living environment of residents.
3. Population density: Nanjing Hecheng is a large residential area with high population density, which will lead to the shortage of some public facilities and services, such as parking spaces and amusement facilities.
