Ouyang Ping and Liu Dayu immediately ran to the service desk.

There are two waitresses at the front desk.

The front desk is directly opposite the main door, and you must go through the front desk to enter the hostel. The door of the hostel is open at night. Most of the people who live in the hostel are business trips, and those who go on business will have some entertainment at night, so they will be late when they return to the hostel; Some people have to get up early in the morning to catch the train.

Liu Dayu walked to the front of the service desk: "Comrade, can I ask you a question?" ”

"Tell me." An older waiter said.

"Who's on duty here at night?"

"We're both on duty here. I'm on duty in the first half of the night, and Xiao Wang is on duty in the second half of the night. ”

"In that night—did you see anyone in or out of the inn?"

"Captain Ouyang, what happened?" The other party knows Ouyang Ping.

"When we got up in the morning and opened the door, we found a note on the floor -- this note -- which was very important to us, and we wanted to know who had secretly stuffed it under the crack in the door." Ouyang Ping raised the note in front of the two people.

"In the middle of the night, a tenant came in and hasn't been out since he came in."

"What kind of tenant is it, do you know it?"

"It's a 307 tenant, I know him, his name is Yin Guikai, he is from Chongqing, when he came in, we also talked a few words, he was drinking with friends, so he came back late. Xiao Wang, in the second half of the night, did you see anyone coming in—or going out? ”

"Sister Zhang, before four o'clock, no one entered or exited the door, and at four o'clock, my upper eyelids and lower eyelids fought, and I couldn't stand it anymore, so I lay on the table and stared for a while—about half an hour." Xiao Wang looked at Ouyang Ping and Liu Dayu with a guilty face, "I'm sorry, I shouldn't have slept." ”

"Xiao Wang, you don't have to blame yourself, you can't blame you, being on duty is a very hard thing, and ordinary people can't stand it." Ouyang Ping comforted.

The person who handed the note saw the opportunity for Xiao Wang to sleep and stuffed the note into the crack of the door. In the second half of the night, it was the time when the person on duty was most likely to be sleepy, and this person knew the situation of the hostel well. Judging from this, the person who delivered the note must have been someone who lived near the hostel.

After breakfast, Ouyang Ping sent Zuo Xiangdong and Liu Wenbin to wait for Ran Shijie in the reception hall of the hostel, and Mafu Street was the only way for Ran Shijie to go to work.

At around 6:50, Ran Shijie pushed his bicycle out of Hoop Barrel Alley.

After walking out of the alley, Ran Shijie got on his bicycle and greeted the owner of the shop as soon as he rode towards the street.

Left to the east and Yoo Wenbin rushed out of the gate of the hostel and stood on the side of the road.

"Ran Shijie, please wait a minute." Left to the east rushed to Ran Shijie and said loudly.

Ran Shijie hesitated for a moment, and jumped out of the car very reluctantly: "What's the matter!" ”

"Our captain asked you something."

"Didn't you ask last night? I'm sorry, there is something important in the unit today, and I can't delay. I'll find out more about it when I get back in the evening. ”

"I'm sorry, we can't delay our affairs, please be sure to cooperate."

Several heads suddenly protruded from the shops along the street. Some are on the lower door panel, some are cleaning.

Ran Shijie looked at his watch, locked the bicycle at the door of the hostel, and followed Zuo Xiangdong and Liu Wenbin into the hostel.
