At 1:30 p.m., Li Qingming, as planned, cycled to the location he intended to pass by and, according to plan, felt the urge to relieve himself.
He parked his bike, grabbed some toilet paper, and smoothly entered the public restroom—all in one go.
After squatting into the planned stall, he rhythmically cleared his throat twice. Next, as planned, a hand reached from under the partition on the right, passing over a planned slip of paper.
"Brother, got any paper?"
Li Qingming then returned the note he had written and hidden inside the tissue packet.
"If you're not hustling on the job and you come out here to take a shit, you're no brother of mine."
After receiving this note, the person in the next stall quickly passed back another one.
"Duke is online, salut, Queen."
Great, just as planned, the secret communication channel that could fool surveillance was now open.
