Qiao Nan did not wish for this incident to affect Peking University or tarnish the reputation of the Zhai family.
Qiao Nan looked anxious. She had already said that the man in the photo was her elder and her father knew about it. The teachers could verify with her father anytime.
Since they were certain that the thread was untrue, even if Qiao Nan did not tell them of the serious consequences, they were willing to block and delete the thread.
It was not difficult to delete the thread. What was difficult was to stop the students in Peking University from discussing this false thread.
Among the teachers who were in the discussion group, one of them was from the computing faculty. After ascertaining that they could do so, the teacher clicked on the school forum to block and delete the thread.
