Do Nanjing people really not go out at night?

This is not true.

Nanjing is a relatively safe and livable city. Many people will go out for activities, shopping, dinner and socializing at night. Nanjing also has many scenic spots and night markets to visit at night. But like other cities, personal safety awareness and precautions are still very important. When going out at night, it is recommended to take some routine safety measures.
