Zhaxi was stunned: "Then what about the threat letter? Saying 'Thirty years ago, do you think no one knows it'?"
Yang Ping shook his head: "That's the issue. If someone is threatening him with this matter, what kind of 'truth' does the threatener know? Is it that Zhou Huaixin concealed the toxicity data? Or did Zhou Huaixin do the right thing but was misunderstood?"
Zhaxi opened his mouth but couldn't answer.
Yang Ping closed the folder and placed it on the table. He said, "Zhaxi, you know, in clinical cases, the hardest to diagnose are not those typical ones, but those that other doctors have misdiagnosed. Because a misdiagnosis will leave a preconceived impression that leads you to gather evidence in the wrong direction."
