Manual ticketing time of Nanjing South Railway Station (window opening time)

The service hours of the North Plaza 1 Floor Hall are from 5: 00 am to 5: 00 pm 1 1: 00, and the rest of the time I will go to the ticket office on the South Plaza 1 Floor to buy tickets or change tickets, but I just went there, and there is no one in the south! Just experienced, the weather in Nanjing this summer, running around, very sour! So wait until 5 o'clock at the earliest. 10!
