last day is the first day for normal passenger.i went to Beijing South Railway Station by subway line4.
the speed is higher than line2 and line 13, and is the similar with line 5 and line 10. althought it is the first day, there is a lot of people and no free seat, but not crowd.
the design of line 4 is convenient for passengers and transfer. i change line 4 from line 2 at Xizhimen station, go downstairs and the platform just there!
at the south railway station, change is convenient too. the exit is near with the ticket windows, and the moving staircase for entrance of rail is not long with the line4 exit.
by the way, some stores in south railway station is not expensive, like holiland cake store. i was hungry and bough some food from there, just used 9 CNY.
at the last, i spend 33 minutes from south railway station to Remin University of China station, what about?
