Three months ago, right after Liang Xiao sneaked into Lin Zhou's room in the middle of the night, surveillance cameras were installed here.
There are cameras at the main entrance and in the living room.
Given the unusual circumstances these days, Zhou Ruilian specially positioned the living room camera to face the sofa. She carried her laptop with her at all times, ready to check on the room.
But when Lin Zhenhua and Li Qingning came over, she closed the laptop, though she didn't turn off the sound.
Shortly after Li Qingning left, Lin Zhenhua was still persistently discussing the "letter of understanding" with her.
A loud noise made them both see the "ugly face" of Li Qingning behind people's back.
They immediately rushed over.
On the first floor, Zhou Ruilian heard Li Qingning sharply scolding Tian Xin: "Who do you think you are? What right do you have to negotiate with me?"
The sound grew closer, and Lin Zhenhua, trailing behind, clearly heard it too.
