Professor Fang was a well-known professor, but compared to Lin Yang he was a nobody. As a Nobel Prize winner, Lin Yang was considered a god by all of Tsinghua University. Professor Fang was afraid of upsetting Lin Yang, otherwise the whole sports department could get in trouble. Therefore, when Lin Yang had come to him, his first reaction had been to blame Dai Li.
Dai Li was not from Tsinghua, but from national team. If he took responsibility for what had happened, Professor Fang and the Tsinghua University sports team would not be blamed. That was why Professor Fang was giving Dai Li a hard time.
Although Dai Li understood why this was happening, he was not happy about it.
If that's how you want to do this, then there is no need for me to try and maintain your reputation.
