Jang, 29, visited his alma mater to give the lecture at a class about understanding philanthropy.
The university established the class this semester to teach about the importance of donations and charity works.
Students reportedly asked for Jang to be invited.
He has been acknowledged at the university for his donations to the school.
Wearing a dark blue suit, Jang spoke for about an hour about the philosophy behind charity work.
In October, the school acknowledged Jang and five of his alumni for their contributions to promoting a charity culture.
