Soon, Zhang Jianjun continued, "I didn't know how long it had been, but I knew it must be very late because there was a building across the river with an advertisement projection on it. My home is right behind that area, so I'm familiar with the operating hours of the advertisement. I clearly saw the billboard across the building go dark before my eyes."
"At what time does the billboard usually turn off?"
"It turns off at midnight and doesn't start up again until 10 a.m. the next morning, so I could basically judge that the time was around midnight," Zhang Jianjun responded.
The police officer looked down to record and said, "Continue."
