It is about15km from the city center. There is no 70 bus at the school gate. If there is no traffic jam, you can get to Feng Dan Street in 40 minutes, which is basically the city center. It is 2 kilometers away from Xinjiekou.
That subway is also an option, but it takes another 20 minutes to walk from the gate of Nanjing Normal University. The friend who said it would take 20 minutes to get to the city center briefly read the conclusion of the newspaper. I've been there several times, and it takes 40 minutes to get to Xinjiekou at the earliest. If you are unlucky and just take the train, the time will be longer. Nanjing is increasing the number of subway trains, and it may arrive in the next 30 minutes. But 20 minutes, no way. . .
I live in Xianlin. If you have any questions, please add 33 14 14 6 to ask me.
