Self-study lottery

A college in North China's Hebei province launched a lottery system for library seats for students preparing for the postgraduate entrance examination, Hebei Youth Daily reported last year.

The school said the measure was taken to curb seating problems. Students without the right to apply for the lottery can go to other rooms of the library for study, the school said.
