On Thursday morning, Yan Feifan got out of bed and turned on his phone, which he'd been forced to shut off last night due to harassment. To his surprise, it started ringing again.
The phone screen showed it was another call from an unknown number.
This genuinely angered Yan Feifan, who hadn't thought much of it the night before.
The harasser was so relentless. 'Do they have a death wish? Don't they know who they're messing with?'
He took his phone to the attic terrace and asked Duan Yu, who was up early exercising, if there was a way to stop the harassment and catch the person responsible.
"Mr. Yan, they're likely using a specific attack program to spam you with calls over the internet."
Duan Yu said thoughtfully, "The military has a cyber warfare unit. They should be able to trace the source of the harassing calls."
"Mr. Yan, I'll report this to my superiors right away."
Duan Yu took Yan Feifan's phone and went back to her room.
