Since this is a promotional lecture at a university, Nan Zhubin chose a case where a university teacher was scammed.
This living environment is closer to the students' daily life, and at the same time, it's more intimidating than "students being scammed" to some extent.
Of course, to avoid being too specific and causing secondary harm to the victim, Nan Zhubin selected a case that did not occur at the current school.
After the conversation transcript appeared on the PPT, Nan Zhubin made a gesture with both hands raised to stop: "Students, the upcoming material involves quite a bit of privacy, so please don't take any pictures, okay?"
This sentence is a warning, but it's also setting a trap.
Upon hearing about privacy matters and being unable to take pictures, even students who were "busy in the middle of something" couldn't resist looking up at the podium.
[Scammer A: "Hello, this is the Taobao Customer Service Center, Customer Service No. 642. Am I speaking with Mr. W?"
