Chang is the father of the Chang Triplets. He is a grouchy man who sometimes complains. He and Proctor Lee are related. He is also one of the contenstants Oscar defeated in the 1977's Spellingbee Championship since he started talking hasty to him and Crandall Smythe. Given the high expectations he has for his children to succeed in life, he appears to fit the stereotype of the Asian-American tiger parent.
