In the evening, Liu Jiahuan sent A-Qing back.

It happened that Yang Quan and Zhu Fengzhang prepared the copper pot mutton, and Liu Jiahuan was also left by Pang Xuelin to eat.

It's only early spring, and everyone has moved the table to the terrace, while blowing a slightly chilly cold wind, while eating the steaming mutton hot pot, it's not too comfortable.

Pang Xuelin, Zhu Fengzhang, and Wei Teng also drank beer.

Zhu Fengzhang originally said that he would not drink it, but he was repeatedly persuaded by Pang Xuelin and Witteng, and he also drank a bottle.

Eat and drink until eight o'clock in the evening, this hot pot feast is over.

After helping to clean up the mess, Liu Jiahuan and Yang Quan said goodbye one after another, and Edward Witten also returned to his small villa.

Pang Xuelin took Ah Qing to the study and tutored her for an hour.

During this time, although Ah Qing followed Pang Xuelin all over the world, his homework has not been left behind.

After Pang Xuelin joined Tsinghua University, he planned to transfer A-Qing to the Primary School Affiliated to Tsinghua University to study.

The academic intensity of Tsinghua University Primary School is many times higher than that of Lingziding Village Primary School, and A-Qing must put in more effort to keep up with the learning progress of the new school.

Fortunately, during this time, he followed Pang Xuelin for most of the world, and Aqing's vision increased greatly, and his interest in learning became much stronger.

Sometimes without Pang Xuelin's supervision, she can sit aside and study quietly for half a day.

Early the next morning, Pang Xuelin and Witten went to the president's office together, signed a work contract with Luan Jingtong, and also met with other leaders of Tsinghua University.

Subsequently, Luan Jingtong took Pang Xuelin and Witten to their respective offices, and Witten's translator and assistant were also ready, and Pang Xuelin didn't have to worry about Witten's affairs for a while.

After placing Witten, Luan Jingtong took Pang Xuelin and a group of faculty and staff of the Department of Mathematics to meet again, Pang Xuelin, as the deputy dean of the School of Science and the head of the Department of Mathematics, is also the boss of the Zhufei Award, no matter how young he looks on the surface, no one dares to show any unconvinced looks.

However, after Pang Xuelin really understood the structure of the Department of Mathematics and the School of Science, he realized that his position as the deputy dean of the School of Science was actually the real power position of the School of Science.

Because the current dean of the Tsinghua School of Science is actually the boss of the Chinese Academy of Sciences, Zhou Guangzhao, this big man is the father of the two bombs, engaged in nuclear physics, and his work at Tsinghua University is only part-time, and he works in the Chinese Academy of Sciences most of the time on weekdays, and basically does not care much about Tsinghua's affairs.

Therefore, Pang Xuelin, the nominal second-in-command, is actually the real person in charge of the School of Science.

At present, Tsinghua University of Science has three departments: the Department of Mathematics, the Department of Physics and the Department of Chemistry.

Pang Xuelin couldn't help but be a little speechless, no wonder Luan Jingtong agreed so easily yesterday, if he wanted to make sildenafil and atorvastatin, he just had to arrange the project to his subordinates.

The 1.5 million yuan that Luan Jingtong said was in place on the third day.

In the following week, Pang Xuelin adapted to the work of the School of Science, and at the same time selected suitable personnel in the Department of Chemistry to prepare for sildenafil and atorvastatin.

All staff members selected for the project must sign the corresponding confidentiality agreement.

Naturally, the professors in the Department of Chemistry have no complaints about this.

This is a big man with a fund of 1.5 million, and he is the real person in charge of the Faculty of Science, so it's not too cool to work for such a boss.

Not to mention, Pang Xuelin also gave an attractive reward.

Sildenafil citrate, chemical name is 1-[4-ethoxy-3-[5-(6,7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4,3d]pyrimidine)]benzesulfonyl]-4-methylpiperazine citrate.

Atorvastatin, chemical name (3R,5R)-7-[2-(4-fluorophenyl)-3-phenyl-4-(phenylcarbamoyl)-5-isopropyl-pyrrole-1-yl]-3,5-dihydroxyheptanoic acid.

These two drugs are basically organic synthesis products, as long as the appropriate technical route is given, the synthesis is not difficult.

Pang Xuelin knows the general process, but the specific synthesis process and technical process need to be done by the project team.

In addition, Pang Xuelin also required that it must be completed within half a year.

In this regard, the old professors who joined the project team agreed immediately.

Although I don't know what Pang Xuelin wants to synthesize these two things for, with a suitable target product and a general technical process, it is not technically difficult to get it within half a year.

Half a month later, Tsinghua's work and life finally settled down, and A-Qing successfully completed the enrollment procedures for the primary school affiliated to Tsinghua University.

Unconsciously, the May Day holiday came as scheduled.

May 1, 1993.

Early in the morning, Pang Xuelin took A Qing, accompanied by Zhu Fengzhang and Yang Quan, and boarded the plane to Lincheng.

Wealth does not return to the hometown, such as brocade clothes at night.

Province G is considered to be his starting place, not to mention, Pang Xuelin still remembers the children of Lingziding Village Primary School, he will definitely go back to see it.

At half past eleven o'clock in the afternoon, the Boeing 737 slowly landed at Lincheng Airport.

After the plane came to a halt on the runway, through the portholes, the flags were unfurled outside, and the welcoming crowd was everywhere.

When Pang Xuelin walked down the gangway and got off the plane, all of a sudden, gongs and drums were noisy, and there were cheers, and two young pioneers took the lead in going up to offer flowers and salute him.

Subsequently, the main leaders of G Province, including Lin Huaiguo, all appeared at the airport to welcome Pang Xuelin home.

At noon, the leaders held a grand welcome luncheon for Pang Xuelin at the provincial government guest house.

In the afternoon, Pang Xuelin, accompanied by Lin Huaiguo, went to Lincheng University and Luo Jianzhong, where Wang Chongqing met them.

At the same time, he also accepted a letter of appointment as a visiting professor of the Department of Mathematics of Lincheng University.

Seeing Pang Xuelin again, whether it was Luo Jianzhong or Wang Chongqing, they were full of emotion.

No one could have imagined that this poor boy, who was just a rural primary school teacher a few months ago, would be able to reach the heights he has today.

Originally, the leaders of Province G and Lincheng University were going to hold a welcome dinner, but Pang Xuelin proposed that he hoped to go to Wang Chongqing's house for dinner in the evening.

Suddenly, no one had anything to say.

After all, when Pang Xuelin was down, it was Wang Chongqing who came to help, and even let Pang Xuelin live directly in his own house.

Now Pang Xuelin proposes to go to Wang's house for dinner, and everyone has only envy.

However, after Wang Chongqing heard the news, he was excited and emotional.

Originally, when he saw Pang Xuelin again, he was still a little restrained, after all, the young man in front of him was now completely different.

Whether it is academic status or political status, Wang Chongqing can only look up.

But seeing Pang Xuelin's statement, Wang Chongqing knew that Pang Xuelin had not changed much compared with before, and he was still the young man who was willing to give everything for the children in poor areas.
