"Reflective vest?" The scorpion's eyes widened, too.

"Yes, it's a reflective vest, because there will be a little reflection, so I remember it clearly."

"What does a reflective vest say?"

"It shows a lot of problems. At least, no one in an ordinary person's home will buy a reflective vest to wear. You just said, "which professions will use reflective vests?" Ye Lingtian directly stood up and asked.

"Traffic police, road administration, sanitation can be used, construction industry can also be used, the rest I can't think of."

Ye Lingtian smoked again, and then he slowly analyzed: "if it's traffic police and road administration, I don't think they will live in such a shabby house. After all, they have a good income, so they can't live in dormitories, so I don't think it's possible. I don't think it's possible for the construction industry. After all, no one will live in a dilapidated house on the construction site, either on the construction site or in a prefabricated house. Of course, this possibility can't be ruled out. Moreover, the construction site doesn't need to use reflective vests for a long time, so it should not wear vests so old. I think the only possibility is sanitation workers. "

"Sanitation worker? Do you mean it's a sanitation worker's house? " Scorpion also reacted at once.

"Yes, it's quite possible. Scorpio, let the leader of Datong District Environmental Sanitation Bureau go to the unit immediately, and I will go there in person. " Ye Lingtian said and went out.

Scorpion Leng Leng, and then followed up, while walking on the phone.

Ye Lingtian and scorpion went to the environmental sanitation bureau directly. When they went to the environmental sanitation bureau, the door of the environmental sanitation bureau was still closed. Obviously, the so-called person in charge had not come at all.

"Why hasn't anyone come yet?" Asked ye Lingtian.

"I've already been informed. I should be in a hurry, but not so soon. Just wait. I also called the person in charge of the Public Security Bureau, and our national security personnel will be here soon. Once there is anything found here, we can arrange the action immediately, and strive to launch the action in the shortest time. "

Ye Lingtian nodded, and then looked at the time. Now it's more than 7:40 p.m., only four hours away from the so-called 24 hours.

Ye Lingtian stood at the door pacing back and forth, his heart is really anxious.

After waiting for more than 20 minutes, several persons in charge of the so-called environmental sanitation bureau came, while the public security and national security personnel had already arrived.

"I'm sorry, leaders, it's a little far away from home, so I'm a little late. Open the door quickly, open the door."

"I ask you, do you have all the sanitation workers registered here in Datong District? In addition, do you have attendance, contact information and home address? " Asked ye Lingtian.

"Well, we have a roster here, but we don't have the detailed information. All the sanitation work in Datong District is contracted to Beijing Renjie Sanitation Service Co., Ltd. these sanitation workers are hired by Renjie company, and they are also responsible for the daily management. We don't participate in the daily management, So we don't know the details. "

"In this way, you can take us to Renjie company immediately. You can let the person in charge of Renjie company go to the company immediately. The sooner, the better. If it's too slow, I guarantee that your official hat won't be worn on your head for a month." Ye Lingtian said, and then said to everyone: "immediately, follow me to this company."

The director of the Bureau of environmental sanitation originally asked him to come after the big leader's call. Although he didn't know what ye Lingtian did, looking at so many policemen and people around him and the big leader who called him, he knew that ye Lingtian was the one he couldn't provoke. So he didn't doubt ye Lingtian's words that asked him to take off his black hat, Scared him straight shiver, a strong call to urge people clean company, very fierce, almost cry, let the other party must be quick.

The actual situation is really fast, ye Lingtian and others to the company not long, Renjie company came to a few people in charge.

"Give me the list of all your sanitation workers in charge of Datong District." Ye Lingtian asked directly after entering Renjie company.

"Good, good, right now, I'll look for it." The other side quickly said, and then began to find in the cabinet.

"Here, here." And then I took out a list.

Ye Lingtian, looking at such a thick stack of rosters, frowned and asked, "how many sanitation workers are there in Datong District?"

"More than 700, that's about the number."

"So much?"

"Our side is relatively backward. In other districts of Beijing, the number of sanitation workers is at least more than 2000. It's normal to have more than 3000."

Ye Lingtian turned over the roster and then asked, "are all the information registered on it correct? Contact number and home address. "

"The phone number is correct, but the home address is not. These are all what they said. We filled them in. It's impossible for us to check whether they live here or not. Besides, it doesn't matter where they live for us, as long as they punch in and out on time every day. "

"Do they need to punch in every day?" Ye Lingtian asked curiously.

"Yes, we have special people driving to patrol every day when we go to work. There is a punch in machine in the car. If we don't punch in, it will be regarded as being late or absent from work."

Hearing this, ye Lingtian thought carefully, and then said, "I ask you, when do you punch in every day? When is the attendance time? "

"The working hours of different streets are different. According to our arrangement, most of them are arranged in the early morning and at night. After all, there is a lot of traffic during the day, which is not safe."

"Well, tell me, were there any absentees last night or early this morning?" Asked ye Lingtian.

"I don't know about this. I didn't take charge of this part. But wait a moment. They register every day. I'll call to ask where the attendance sheet is. I'll find it for you." Said the other party began to call, and then went to another office inside, ten minutes later took a attendance sheet handed to ye Lingtian.

The other side turned over the test form, and then said: "the attendance of last night and this morning are all here. There are three people absent from work, one asking for leave."
