Eight years ago, on that night, Fu Hanshen had opened QQ software to exchange his latest research insights with his own student. He had sent the compiled document to Song Fei for her to look through and wanted to listen to her opinion.
Fu Hanshen saw that Song Fei had accepted the document. Thinking that she should have finished reading it, he asked her for her opinion.
The message was like a rock sinking into the ocean and there was no response.
At that time, Fu Hanshen felt that it was strange and thought that Song Fei had fallen asleep from playing too much during the day, so he logged out of QQ and turned off his computer. He had just switched off his computer when he received a call from his good friend. His friend said, "Hanshen, did Song Fei go to Bijiang City with her family?"
