Is the Nanjing subway free in May 1 Day?

It is not free. The subway has always been charged and is an important track of the city. There is no free policy, so it is not free for passengers to take the subway in the city during the May Day holiday in 2023. The specific charge depends on the mileage. When taking the subway, you should pay attention to the overall design layout of the subway entrance and exit to avoid the wrong exit. At the same time, please stand outside the yellow line to check the ticket, and please put the one-way ticket into the recycling port when leaving the station.
