"Reflective vest?" Scorpion also widened his eyes.

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

“What does a reflective vest mean?”

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

"It can be used by traffic police, road administration, and sanitation, and it can be used by the construction industry, but I can't think of the rest."

Ye Lingtian smoked again, and then slowly analyzed himself: "If it were the traffic police and road administration, I wouldn't think they would live in such a dilapidated house. After all, their income is pretty good and they really can't live in a dormitory, so I don't think it's possible. In the construction industry, I don't think it's possible. After all, there will be no possibility on the construction site. After all, there will be no one living in a dilapidated house. They either live on the construction site or live in a prefabricated house. Of course, this possibility cannot be ruled out. Moreover, the time required for a reflective vest on the construction site is not much, so it shouldn't be worn so old. I think the only possibility is sanitation workers."

"Sanitation worker? Do you mean that the other party is in a sanitation worker's house?" Scorpion also reacted suddenly.

"Yes, this possibility is very high. Scorpion, let the leaders of the Datong District Environmental Sanitation Bureau go to the unit immediately, and I will go there in person." Ye Lingtian said as he walked out.

Scorpion was stunned for a moment, then followed and called while walking.

Ye Lingtian and Scorpio went directly to the Sanitation Bureau. When they arrived at the Sanitation Bureau, the Sanitation Bureau was still closed. Obviously, the so-called person in charge had not arrived yet.

"Why haven't anyone come yet?" Ye Lingtian asked.

"I have asked someone to notify me and I will come here immediately, but it's not so soon. Let's wait a little longer. I also called the head of the Public Security Bureau, and the people from our Guoan will arrive immediately. Once there is anything found here, we can arrange the action immediately and strive to take action in the shortest time."

Ye Lingtian nodded, then looked at the time. It was already past 7:40 in the evening, and it was only four hours before the so-called twenty-four hours.

Ye Lingtian stood at the door and paced back and forth, and he was indeed anxious.

After waiting for more than twenty minutes, several so-called sanitation bureau leaders came, but the public security and Guoan people had already arrived.

"I'm sorry, I'm sorry, my leaders, my home is a little far away, so I'm a little late, so I'm hurried to open the door and open it."

"I'll ask you, do you have registered all the sanitation workers in Datong District? In addition, do you have attendance, contact information and home address?" Ye Lingtian asked.

"This, we have a roster here, but we don't have these detailed information. All the sanitation work in Datong District was contracted to Beijing Renjie Sanitation Service Co., Ltd. These sanitation workers were hired by Renjie Company and were also responsible for daily management. We do not participate in daily management, so we are not clear about these detailed information."

"In this way, you will take us to this clean company immediately. If you ask the person in charge of the clean company to go to the company immediately, the faster the better. If it is slower, I promise that your official hat will not 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 Environmental Sanitation Bureau answered the call from the leader and asked him to come here. Although he didn't know what Ye Lingtian was doing, looking at the many policemen and people around him, as well as the tone of the leader who called him, he knew that Ye Lingtian in front of him was someone he couldn't afford to offend, so he didn't doubt Ye Lingtian's words that asked him to take off his black hat. He was so scared that he shivered. He kept calling the person in the cleaning company. He was very fierce and almost cried, so he told the other party to be quick.

The actual situation is indeed fast. Not long after Ye Lingtian and others arrived at the company, several persons in charge came to Renjie Company.

"Take me out the list of all your sanitation workers in charge of Datong District." Ye Lingtian asked directly after walking into Renjie Company.

"Okay, okay, I'll look for it right away." The other party said quickly, and then began to search in the cabinet.

"Here, here." Then I took out a list.

Ye Lingtian frowned at the thick stack of rosters and asked, "How many sanitation workers are there in Datong District?"

"More than seven hundred, almost this number."

"so much?"

"We are relatively backward. In other areas of Beijing, the number of sanitation workers is at least more than 2,000, and it is normal for more than 3,000."

Ye Lingtian flipped through the roster and asked, "Are the information registered on this one correct? The contact number and this home address."

"The contact number is correct, but the home address is not certain. These are all filled in by them themselves. We can't verify whether they live here or not. Besides, where they live is not important to us, as long as they check in and get off work on time every day."

"Do they need to check in every day when they go to work?" Ye Lingtian asked curiously.

"Yes, every day we go to work, we have special people driving to patrol. There is a clock machine in the car. If we don't check in, we will be considered late or absent from work."

Ye Lingtian heard this and thought carefully, then said, "Then I ask you, when do you check in every day? When do you attend?"

"This... the working hours of different streets are different. According to our arrangements, most of them are arranged in the early morning and evening. After all, the traffic flow during the day is not safe."

"Okay, then tell me, did you absent from work last night or early this morning?" Ye Lingtian asked.

"I don't know this...I don't know about this. I didn't take care of it. But wait a moment, they have registered every day. I call to ask where to put the attendance form and I'll find it for you." As he said that, the other party started to call, and then went to another office to flip through it. After about ten minutes, he took an attendance form and handed it to Ye Lingtian.
