Pao studied in the Faculty of Agriculture at a famous university. In the building where Pao went to study every day, there was a cannabis cultivation house. Pao became curious and wanted to try it, so Pao took some cannabis back to his room. Pao became addicted to it and went to bake cannabis at the cultivation house and was hooked. But this time, the university's closed-circuit TV camera (CCTV) saw that Pao had stolen some cannabis from the cultivation house. Pao was taken to jail, where the cannabis wore off, and Pao saw his parents while he was in prison, but they couldn't do anything.
