Li Tangshan finally successfully passed the selection and was arranged in the temporary group of Qian Xuesen of the 507 Institute.

A week later, Li Tangshan was going to report for duty, and Li Tangshan used his free time to go to Beihang to find tutors and classmates. Xu Xingning coaxed Li Tangshan to invite a guest to celebrate, and the classmates also took Li Tangshan to the Chaozhou restaurant in the Aerospace Bridge to slaughter Li Tangshan.

Li Tangshan sent the classmates back to school, and Li Tangshan had a phone call with Uncle Zhuo to report the recent situation to Uncle Zhuo. Uncle Zhuo said that the doctor last time, he arranged it through his comrades-in-arms, and sent Uncle Zhuo another batch of Meixian Shikeng's spring tea to Li Tangshan this year. Li Tangshan asked Xu Xingning to help him collect the tea last time, but he just forgot to ask him. Li Tangshan asked Uncle Zhuo for the doctor's address, and decided to call Xu Xingning to visit the barefoot doctor together.

After Li Tangshan finished talking to Uncle Zhuo, he made another phone call to Xu Xingning and asked him to find someone with him.

Li Tangshan was waiting at the school gate of Beihang University, and saw Xu Xingning running over with two cans of tea. Li Tangshan called a taxi and gave the address provided by Uncle Zhuo to the driver: "No. 11 Tonggu Lane, Dongzhimen!" Yoyo! ”

Li Tangshan and Xu Xingning chatted happily all the way, and the driver interjected from time to time to say a few words. Later, it will become the driver's personal political opinion conference, Zhongnanhai's important officials seem to be relatives of his family, and the national policy must be handled by the driver's boss, Li Tangshan and Xu Xingning suddenly took turns to be the audience.

"Okay, you've arrived at your destination!" The driver shouted.

Li Tangshan paid the fare and began to look for the address provided by Uncle Zhuo, Li Tangshan felt that someone was always monitoring his every move from afar. However, no suspicious person was found. Li Tangshan took Xu Xingning around Tonggu Lane, and then got on a self-rented car to go around the city of Beijing. After Li Tangshan felt that those people were no longer with them, he returned to Tonggu Lane.

Xu Xingning didn't understand and asked Li Tangshan why he came back again.

Li Tangshan said: "Nothing? When I returned to Beijing this time, I always felt that someone behind me was watching my every move. But there is no real finding of a suspicious person, and it is not known whether the other party is friend or foe. Still to be on the safe side, I made a few more turns. ”

Li Tangshan didn't get out of the car this time, and saw the barefoot doctor's family sorting out medicinal materials at the entrance of the alley, and they had made a traditional Chinese medicine clinic in Beijing.

Li Tangshan asked Xu Xingning to send two cans of tea to the barefoot doctor and left a phone number? Let them have any needs and go directly to Xu Xingning.

Xu Xingning returned to the car and gave Li Tangshan the phone number, and then went back to Beihang.

Li Tangshan saw that the barefoot doctor was living well in Beijing, and decided not to worry about their peaceful life.

But a week passed quickly, and Li Tangshan packed his luggage and prepared to report to the 507 Institute.

The leaders of the 507 Institute still attach great importance to Li Tangshan's internship and specially sent a vehicle to pick up Li Tangshan.

After picking up Li Tangshan's car and driving directly to the 507 Institute, Li Tangshan found that it was very tightly guarded, with three layers inside and three layers outside like a military restricted area. After the driver parked the car, he took Li Tangshan directly to the director's office.

Director Chen Youxin is a very enlightened leader, kind and trustworthy, just like Li Tangshan's grandfather, Li Tangshan's affection for him has risen rapidly. Director Chen Youxin brought Li Tangshan into the office when the driver brought him into the office, immediately put down the pen in his hand, stood up and walked towards Li Tangshan, and stretched out his hand to shake hands with Li Tangshan: "Li Tangshan, you are the first time since the establishment in 1968 that an overseas Chinese student has come to the unit for an internship. You are welcome to join our 507 family. ”

"Xiao Wu, you take Xiao Li to the guest house and arrange his daily life." Director Chen called a handsome young man aged 27-28.

"Wu Zuoxin, hello!" The young man introduced himself.

"Li Tangshan, excuse me!" Li Tangshan shook hands with him cordially and greeted him.

Wu Zuoxin is a young scholar with a very calm personality, although he doesn't say much, he can get to the point in every sentence, and he is also a very effective assistant to Director Chen.

"Xiao Wu, you take Tangshan classmates to take a look around, and by the way, introduce the situation in the institute?" Director Chen said to Wu Zuoxin.

Director Chen turned his head to Li Tangshan again and said, "Tangshan, I have a meeting in a while, you can go around with Xiao Wu to familiarize yourself with the situation!" ”

Li Tangshan said very politely: "Thank you, Director Chen! ”

Director Chen picked up the folder on the table and went out with the driver.

After Chen Youxin left, Wu Zuoxin briefly introduced the history of the 507 Institute and Li Tangshan's task arrangement, "507 Institute" is the abbreviation of the original "507th Research Institute of the Chinese People's Liberation Army", when the 507 Institute was established in April 1968, the full name of the 507 Institute was "Institute of Aerospace Medicine and Engineering", and later changed its name to "Beijing Institute of Aerospace Medical Engineering", and Qian Xuesen was a subordinate unit (that is, the "China Academy of Space Technology") when he was the old president of the old "Fifth Research Institute of the Chinese People's Liberation Army".

Wu Zuoxin continued: "In the overall plan for the development of spacecraft in China, the 507 Institute participates in the comprehensive research of aerospace medicine, as well as the selection, training and training of astronauts. ”

Li Tangshan asked curiously: "Which unit was I assigned to intern in?" ”

Wu Zuoxin flipped through the records and replied to Li Tangshan: "That's right, Li Tangshan!" You are arranged to intern in the "Human Potential Group", which is also known as the "Qian Xuesen Temporary Group", and the scientific research team lasts for half a year. ”

Li Tangshan nodded: "Where is my place of work?" ”。

Wu Zuoxin flipped through the records again and said, "Your intern is at the test base near our Shentangyu in Huairou, not far from the Miyun Reservoir? That place needs to be kept secret. I'll send a car with you in a moment. ”

The capable Wu Zuoxin arranged the vehicle in three and two clicks, a black MVP with all Wu Zhang.

It took 1 hour to walk from the Sky City to the Miyun Reservoir, the scenery along the way was very beautiful, and the sky was blue. The more the car drove, the more it went into the mountains. I don't know how many checkpoints I passed, but after the turn of the mountain road, a current office appeared in front of me, and Wu Zuoxin signaled that Li Tangshan could get off the bus. Wu Zuoxin led Li Tangshan into the guest house next to the office, and the hospitality was also very high-end, like a star-rated hotel.

"Your team works in the bungalow at the back of the host, and this is your work ID, which contains all your biometric information," Wu Zuoxin instructed carefully. "In another moment, I will introduce a colleague from your group to you, you go to the room first to put down your luggage, and I will wait for you in room 505 in ten minutes."

Li Tangshan quickly walked to the room in the guest house, which was similar to a general apartment hotel room.

Li Tangshan put down his luggage and looked at the bungalow behind the house through the window, the bungalow of a utility room similar to a laundry room, Li Tangshan felt very lost. This is much worse than the research institutes of MIT and NASA, and even worse than the general laboratories of Beihang University.

"The construction of the space city is so beautiful just now, but what is the small bungalow in the back? More like a small utility room. My practice room is bigger than his. Li Tangshan said to himself.
