Most of the tranfer stations of Shanghai metro are designed properly no other than the Zhongshan Park where the Line 2 and Line 3 could transfer to each other. We left from the People's Square(Line2) to the
Shilong Road (Line3). When we transfered at the Zhongshang Park Station, it was a challenge for our physical strength. First, took a long way hastily and then climbed up a long stairs to the upper level where the station of Line 3 was. It almost took 10 minutes for a young lady. So, I think that they should improve the transfer station better!
