If it were not for an accident in March this year, maybe Luo Caixia would never know the truth 5 years ago: in the college entrance examination in 2004, she was not admitted by any colleges or universities while her classmate Wang Jiajun who had taken her place was admitted to Guizhou Normal University's major of ideological and political education. Since then, their fates have changed. Luo Caixia was forced to study again for a year and then passed the exam to Tianjin Normal University. In 2008, Wang Jiajun graduated smoothly. However, Luo Caixia who should graduate this year has to face a serial of problems because her ID card was stolen, such as being disqualified from obtaining the teacher qualification certificate.
