First, I have no objection to what you said about Comrade Jia Yimin's academic performance. However, the news website of Huaqiao University particularly emphasizes that he is a "doctoral tutor". I can tell you responsibly here that he is not in Jinan University.
Secondly, you said, "If it weren't for an accident a few years ago, he would have been the president of Jinan University six or seven years ago." I don't believe this. Unless you prove that you are the leader of the Overseas Chinese Affairs Office, how did you come to this conclusion? The chairman is decided by the Party Group of the State Council Overseas Chinese Affairs Office. Have you appointed him?
You said Jia Yimin was "modest", but I only heard of his "tough style". You said, "His arrival is a blessing for teachers and students of Huaqiao University." I'm not sure about that either. It's just that I saw on Huaqiao University News Online that a girl jumped off a building in Xiamen campus the night the appointment was announced. I know it's just a coincidence.
