Ye Zhenzhen suddenly remembered that she had read an introduction to the Tuanshan Forum on the Internet, so she asked: "Is it the Tuanshan in the 'Infectious Disease Tuanshan Forum'?"

Wang Lichuan: "Well, it's that Tuanshan, Tuanshan means the mountain of unity, Tuanshan has witnessed the history of the development of the Institute of Infectious Diseases, the park where the China Center for Disease Control and Prevention is now located, originally there was only one unit of the Institute of Infectious Diseases, and later after expansion, the current China Center for Disease Control and Prevention was formed, and the old laboratory building of the Institute of Infectious Diseases is the three-story experimental building of blue bricks and gray tiles that we just passed, which was still built with the aid of the former Soviet Union.

Fang Nana seemed to be very interested in this Tuanshan, and asked Wang Lichuan: "I have also heard of the Tuanshan Forum, isn't it an academic annual meeting held every year by the Institute of Infectious Diseases, and what does this have to do with the Tuanshan in front of me?"

Wang Lichuan: "The Tuanshan Forum just borrowed the name of Tuanshan, in fact, the Tuanshan Forum was only held in 2008, every winter, the Institute of Infectious Diseases will invite top infectious disease experts from all over the world to Beijing to participate in the annual academic meeting, although I am not in the Institute of Infectious Diseases, but I am still very impressed by this academic annual meeting, because, every year when it comes to the annual meeting, the big bulls in the infectious disease academic community will come to Beijing, and the whole Institute of Infectious Diseases people are a little excited. ”

Ye Zhenzhen was also looking forward to such an academic event, and thought to herself, if she could stay and work here, then she must go and see it.

Ye Zhenzhen looked up at the top of Tuan Mountain, the spire of the pavilion loomed in the shade of trees, Gao Wei looked at Ye Zhenzhen, then looked at the top of the mountain, estimated the time again, and said, "Why don't we go to the top of the mountain to have a look." ”

The four of them hit it off, set off towards the top of the mountain, strolling all the way, but it took about ten minutes to reach the top of the mountain, standing in the pavilion on the top of the mountain, the entire central compound had an unobstructed view.

The breeze was blowing, the leaves on the top of the mountain rustled, and the four of them looked at the scenery from afar, Fang Nana asked Gao Wei beside her, "Why did you take the exam for so long just now?"

Gao Wei: "It's not difficult, it's just to identify some radiation sources, it's very simple. ”

Fang Nana: "Then you have been delayed for so long, you entered the examination room earlier than us, but came out later than us, and it is simple to say, it seems that the radiation institute, even if it is a doctor, is not so easy to enter." ”

Gao Wei smiled and explained: "After the exam, I went to find my classmate Wang Lichuan, thinking that he was familiar with this place, so I asked him to introduce it to us, so I delayed for a while. ”

Fang Nana originally wanted to hit Gao Wei a few words, but when she heard that Gao Wei was kind enough to find a classmate to be a tour guide, she swallowed the words of the blow back into her stomach, and asked instead: "Is it very simple for you to identify the radiation source in your skill test?" ”

Gao Wei: "As the saying goes, interlacing is like separating mountains, I am a radiology major, and of course identifying the radiation source is the most basic. ”

Fang Nana asked again: "Is the radiation source the X-rays we usually go to the hospital to take and the like, as well as the computers and mobile phones we use?"

Gao Wei: "A radiation source is a substance or device that emits ionizing radiation. Broadly speaking, any substance or device that can emit various kinds of ionizing radiation, such as cosmic rays, can be regarded as a radiation source. However, it is customary to refer to radioactive sources with high radioactivity depths used for γ flaw detection, radiotherapy, radiation processing, etc., as radiation sources, and the radiation from our daily mobile phones and computers can be ignored......

Ye Zhenzhen listened to Gao Wei talking about the exam questions, but her eyes looked away, and the scenery of the entire CDC fell into her eyes, there was an artificial lake next to Tuan Mountain, surrounded at the foot of the mountain like a jade belt, listening to professional knowledge in her ears, looking at the beautiful scenery in her eyes, and feeling comfortable in her heart, suddenly, "Jingle bell ......", the mobile phone rang.

Ye Zhenzhen took out her mobile phone from her pocket and looked at the screen, which showed the name of "Nan Zhiqiao".

Ye Zhenzhen picked up the phone, and Nan Zhiqiao's calm voice came from the opposite side: "Ye Zhenzhen, where are you now?"

"The top of Tuan Mountain. ”

"It's windy today, what are you doing at the top of the mountain?"

"I visited the central compound with a few friends, and when I saw Tuanshan, I came up, what are you looking for me?"

Nan Zhiqiao was silent for two seconds and said, "There is an artificial lake at the foot of Tuan Mountain, and there is a guardrail open space in the southeast corner of the lake, you wait for me there." ”

Without waiting for Ye Zhenzhen to answer, Nan Zhiqiao hung up the phone, Ye Zhenzhen muttered in her heart, I said that I am not suitable for working in the disease control system when we met just now, and now I want to meet alone, Nan Zhiqiao will not want to persuade me to leave directly, this is too unkind, although the two do not have much intersection, but they have also had the experience of living and dying together, Nan Zhiqiao will not be so unkind......

Ye Zhenzhen was worried alone, and Fang Nana, who was not far away, suddenly asked, "Zhenzhen, whose phone call is it?

Ye Zhenzhen put away her phone and shook her head, "No, it's a friend's call." ”

Gao Wei: "The results of today's skills test will not be announced until the end of the whole exam in the afternoon, and now it is just noon, so I won't call so soon." ”

Looking at the sun in the sky, hanging in the sky, Fang Nana felt her stomach growl, Fang Nana said to Ye Zhenzhen: "Zhenzhen, it's noon, let's go to the central restaurant for lunch together?"

Ye Zhenzhen remembered the agreement with Nan Zhiqiao and refused, "You guys go first, I just had an appointment with a friend." ”

Fang Nana was quite regretful, "Then let's leave each other's phone numbers so that we can contact each other in the future." ”

The four of them left each other's phone numbers, and went down the mountain together, at the intersection of the mountain, the four of them parted ways, Fang Nana went to the central restaurant with Gao Wei and Wang Lichuan, and Ye Zhenzhen went to the lake alone.

The artificial lake at the foot of the group mountain is sparkling under the sun, Ye Zhenzhen walks along the cement road at the foot of the mountain, all the way to the southwest corner of the artificial lake, standing at the guardrail, looking at the whole artificial lake, the lake water is clear, and there are groups of red koi playing in the lake.

Ye Zhenzhen could see that she was fascinated, and she didn't notice a person walking behind her, who walked behind Ye Zhenzhen, stood still at a distance of ten steps, and quietly looked at Ye Zhenzhen's slender silhouette, and was a little distracted.

After a few minutes, the person who came was the first to break the silence and said, "Ye Zhenzhen." ”

Ye Zhenzhen turned around, and saw Nan Zhiqiao at a glance, still in a blue suit and white pants when she first met in the morning, with a refreshing appearance, Ye Zhenzhen smiled and said, "Senior Nan, you are here." ”

"Hmm. ”

"You called me here, what's the matter?"

Nan Zhiqiao asked straight to the point: "Why did you interrupt your studies? Did you encounter any difficulties? If you have difficulties, I can help you." ”

Ye Zhenzhen's heart was moved, and at the same time, she felt guilty for her speculation about Nan Zhiqiao's intentions just now, but if she told the truth, Nan Zhiqiao might let herself go back to school to study for a doctorate, and she must enter the disease control work this year, Ye Zhenzhen shook her head and said, "It's not difficult, it's just that I want to join the work." ”
