On June 5th, the Education Bureau of Nanchong City, Sichuan Province found that the college entrance examination papers were stolen during routine inspection. The fence of the window outside the house where the test papers were stored has been deformed, and seven iron boxes inside the house have been pried open. Among them, 6 test papers of Chinese, Mathematics (liberal arts), English, Literature Synthesis and Science Synthesis were lost. After the documents were lost, the relevant departments quickly blocked the scene, and the Criminal Investigation Brigade of nanbu county Public Security Bureau quickly came to the scene according to the instructions. After searching the surrounding area of the crime scene for half an hour, the public security department found that these test papers were found in the trash can 150 meters away. After checking these found papers, the staff found that Zhang Wenke was still missing a math paper. It turned out that it was Bai Yang, a candidate who was preparing to take the college entrance examination. After asking about the location, he arrived at nanbu county Admissions Office in Nanchong at 10: 00 pm. He took a few papers at random and left in a hurry. On the way to distract the police, he threw all the other papers into the trash can, leaving only Zhang Wenke's math paper. But when he entered the examination room, he found that the paper in his hand was not paper at all, because the paper was stolen, so the spare paper was used for the college entrance examination in 2003.

The college entrance examination is highly confidential. The teacher who gave the question will be isolated after completing the work until the end of the college entrance examination; Workers who print test papers can't contact the outside world until the exam is over and the printing task is completed; The transportation process of college entrance examination papers is more strict. During the transportation of test papers by the motorcade, there is full video and GPS positioning, which is convenient for the enrollment examination institutions to monitor the test papers in real time.
