 CONT: When Zhou Yu and Zhang get off the train at the deserted Xan  Hu Station she is wearing brown shoes. They set off to look for Xan  Hu Lake. While walking on the grassy slopes looking for the Lake,  Zhou Yu is now wearing sneakers with blue tops and thick white  rubber soles. When they get back to the train station, she is  wearing brown shoes again. Her pocketbook is very flat and not fat  enough to hold a spare pair of footwear.
