How To Get There: You'll need to take Line 1 to Xinzhuan Station (around 10 stops from Shaanxi Nan Lu Station). Then from there you can either transfer to Line 5 and take it to Zhuanqiao Station or take a shuttle bus. The shuttle buses start at the end of the South Square of Xinzhuang station, but they are pretty hard to spot and look like other city buses. The tennis center is a 20 minute walk from Zhuanqiao Station or a short taxi ride.
The shuttle buses going to the tennis center run from 11am-7pm on the tournament dates. Returning buses run from 4pm-10pm.
A schedule of the event and match-ups can be found here on the Shanghai Rolex Master's website. Tickets for the semis on Saturday and finals on Sunday are 1080rmb on SmartTicket.
