A college campus in East China has converted a gymnasium into a mailroom to cope with the sharp increase in parcels for students who bagged bargains on Singles Day, the online shopping festival.

Zhejiang University's Zijingang campus in Hangzhou has installed 200 racks to store the 200,000 packages expected to arrive in the two weeks following Nov 11, the date of the event.

"We handle 10,000 parcels on a normal day, but now we have to deal with up to 20,000 or more," said Wang Zhongjuan, a senior employee at the campus mailroom.
