In the final few episodes of "Fantastic Doctors," there was a somewhat unrealistic storyline. It turns out that Chen Hui had a senior fellow student named Ding Ming Zhang who wanted to add his own name to Chen Hui's research paper. This way, Ding Ming Zhang could gain professional recognition and pursue an academic career.

This situation may sound unbelievable, but it doesn't harm anyone. Ding Ming Zhang wasn't trying to impersonate Chen Hui's senior fellow, but simply wanted to include his name to acknowledge the assistance he provided. This would make it easier for Ding Ming Zhang to gain professional recognition and secure his position at the university. The paper would still be credited to Chen Hui, and no one could take it away from him. This is commonly known as being the third or fourth author of a research paper, for those who understand the academic conventions.

This falls under the realm of interpersonal relationships, where helping others can also benefit oneself. Of course, some people are resistant to such arrangements. In Chen Hui's case, he completely fails to understand and accept it. He questions why his senior fellow's name should be added when he didn't actually help him. Why should I accommodate him just because he took care of me? This is how Chen Hui thinks.

Ding Ming Zhang wanted to look after his own student, but it seems that he faced some difficulties in reality. In the end, Chen Hui decided not to add his senior fellow's name, and his senior fellow didn't fare well. The unpleasantness between Ding Ming Zhang and Chen Hui arose from this situation.

Ding Ming Zhang heard about Chen Hui's dismissal from the hospital due to plagiarism allegations, and that's when he stepped forward to clear Chen Hui's name. Ding Ming Zhang can be considered a good teacher, as he never intended to hinder Chen Hui's progress. If Chen Hui were a normal person, their teacher-student relationship might have been better.
