As a teacher he took an almost sadistic approach to his job and often intimidated his students with his unbalanced behavior.
This attitude surfaced again when he was hired as a school security guard and abused his authority on a larger scale. On the other hand, he also experiences bouts of depression, self pity and neediness.
This contrasts his louder and more obnoxious personality suggesting that it's just a mask for his own insecurities. This was passively shown when he used self-deprecating humor to mock his own shortcomings. His time as a student illustrated how desperate Chang could be as he struggled to be accepted by the study group. It's hinted thatmonkey gas that he had inhaled had started to poison his mind. It fueled his delusions and pushed the worst of aspects of his personality to the extreme. In his later years at school he seemed to calm down when he joined the Save Greendale Committee. Despite a few relapses he considered the committee his friends and liked who he was when he was with them. At the end of the 2015 semester at Greendale he announced to his colleagues that he was gay. It was unclear whether this was a legitimate declaration or yet another example of his capricious nature.Ĭhang has been a long time employee at Greendale.
