On the early morning of June 9, Li Mingquan (pseudonym) and his wife stormed to the enrollment office of Songyuan City in Jilin Province to make complaints for their son. In yesterday's college entrance examination, their son Li Shuang (pseudonym) had his test paper plagiarized by a candidate sitting behind him, and thus failed to finish the test in time. Moreover, his answer sheet was also torn apart, which seriously affected his score in this subject.
