Manager Wang transferred the surveillance very quickly. Within ten minutes, he called Jiang He and asked him to take Tang Huanxi and others to the surveillance room.
The monitor in the monitoring room showed the deceased’s activities in the hotel at different times.
According to Manager Wang, the deceased was a side dish cook in the kitchen. Because he received a call from Jiang He at noon, he arrived at the hotel at around two o'clock.
During this period, he worked in the kitchen almost all the time, and the video was also recorded. He only went out a few times, always to the toilet.
While going to the toilet, I didn't come into contact with anyone.
Except for the chefs in the kitchen, these chefs have been controlled by Jiang He's people and are being interrogated.

At 4:58, Tang Huanxi suddenly stopped.
At this time, the deceased in the picture had just walked out of the bathroom, walked quickly through the passage, and walked into the kitchen.
"Go back and freeze it when he first came out."
Tang Huanxi spoke.
"good."
When the staff called back frame by frame and fixed the scene in the men's bathroom when the figure of the deceased had just appeared, Tang Huanxi suddenly pointed his finger at his face:
