Haidian Transportation

There are actually two west gate entrances to Peking University; one exclusively for automobiles and motorcycles and the other for pedestrians and bicycles.
The pedestrian entrance leads to the Sackler Museum on the left after you cross the bridge shown in my photo. Continue walking east behind the Sackler Museum to reach "The Lake with No Name Yet" (Wei Ming Hu).
If you walk right after crossing this bridge you will come to the Peking University museum and from there you can cross a small bridge and continue south to the foreign student dormitories (Shao Yuan) where good cheap meals can be had at the cafeteria behind the main building.
