How can I get to Nanjing International Expo Center (No.5 Bailongjiang West Street, Nanjing) from Zhonghua Gate by bus? Urgent problem!

First of all, there is no direct bus to Bailongjiang West Street. The most convenient way to get to Zhonghua Gate is to take the subway southbound and get off at Tong Yuan. After leaving the station, there is a 10 intersection with a viaduct. The first intersection on the right is Bailongjiang West Street.

What I want to say is why I want to go there to find a job. It is far and wide. There are too many job fairs in urban areas, basically three or four every week. Why not go from near to far?
