In July, Shen Qi led a volunteer team of two graduate students to fly to Xining.

The mayor of the city cordially received Shen Qi and his entourage at the city hall and invited the Yanda volunteer team to the banquet.

"Thanks to Mayor Gao's hospitality, let's skip the meal, and we will go directly to Maduo County to carry out social service work. Shen Qi politely refused Mayor Gao's dinner, and his heart had flown to Maduo County, the source of the Yellow River.

"Let's not eat outside, just have a light meal in the canteen inside the city hall. "Mayor Gao is very enthusiastic, and when he receives a big scientist like Shen Qi, he has to arrange for the scientist to have a full meal in the provincial capital city before going on the road.

"Try to keep it simple. Shen Qi was embarrassed to continue to resign, so he took two graduate students and had a working meal at the city government.

During the banquet, the city's leading group toasted with Shen Qi, saying that Professor Shen must drink this bowl of barley wine, which is the local custom of receiving VIPs.

Before you get to work, drink first.

Shen Qi is a very principled person, he drank this bowl of barley wine, and respected the local folk customs.

"Leaders, I have already drunk the welcome wine, and it will be a violation of work discipline to drink it again. "Shen Qi's amount of alcohol is no problem to drink a jar of barley wine, this wine is not bad, but Shen Qi only drinks a bowl until the end, after all, he is working.

"Understand and understand, Professor Shen is indeed a great scientist who is strict with himself. The city's leadership team admired Shen Qi very much, and everyone replaced wine with tea and talked freely.

Shen Qi led a team to Maduo County this time to carry out another social service work.

Maduo County is a national-level poverty-stricken county, with backward infrastructure, economy, and education.

Since 1999, Yan University has sent graduate student teaching teams to Shaanxi, Gansu, Ningbo, Qinghai, Tibet and other regions in the western part of the motherland to carry out volunteer teaching activities.

There is a graduate student in the Department of Mathematics of Yan University, who came to Maduo County in 1999 to teach, and he has worked without regrets for more than 20 years, dedicating his youth to the construction of the western region.

The graduate student passed away last month, dying of cancer.

A week before his death, he completed an essay that focused on: "From the richest county to the poorest county, what have we done to Maduo?"

Shen Qi respects this graduate of Yan University School of Mathematics very much, and he led two graduate students to the place where their predecessors once fought, one is to inherit the glorious tradition of Yan University, and the other is to conduct field trips, why did the richest county become a poor county in more than ten years?

Shen Qi's trip to the west is half social service, and the other half is scientific research.

A hard-core SUV drove away from the city hall in Xining, and Shen Qi and two graduate students sat in the car.

Shen Qi found that there were two off-road vehicles in front of him, followed by three of the same model. The vehicle behind the palace that opened the road has a green O license plate.

Shen Qi was unhappy: "We go deep into the grassroots to do services, not to show off our might, what are you doing with so many cars, let them all go back, don't follow us." ”

There were a total of four people in the car, in addition to Shen Qi and the three of them, there was also a driver.

The driver is not an ordinary driver, he is Mayor Gao's No. 1 driver.

Driver No. 1 received an important task from the mayor this time, escorting Shen Qi and his entourage to Maduo safely, and then taking Shen Qi back to Xining safely.

Driver No. 1 explained while driving: "Professor Shen, the province and city attach great importance to your operation to support the western region this time, so they sent a team to Maduo to assist you in carrying out various tasks. ”

"The kindness of the province and the city, we understand it. Shen Qi picked up the walkie-talkie in the car, dialed into a channel, and called: "Attention to all units, I am Shen Qi, except for the O00020 vehicle, the rest of the vehicles please turn around in front and return to the city and provincial government." ”

The O00020 vehicle was the one that Shen Qi and the others were riding, and Shen Qi personally gave instructions to let the rest of the vehicles return.

After a moment of silence on the intercom, a voice came out: "Hello Professor Shen, I am Yao Ning, deputy director of the Provincial Department of Education, and the instructions of the province are to let our field team be sure to assist Professor Shen in completing this grassroots activity." ”

Shen Qi said politely: "Yao Hall, it is enough to ask the province to assist in arranging local assistants who are familiar with the situation in Maduo County." Repeat, all units, please pay attention, I am Shen Qi, except for the O00020 vehicle, the rest of the vehicles should turn around in front and return to the city and provincial government immediately. ”

There was silence again on the intercom.

Two minutes passed, and the green O convoy passed a U-turn, but none of the cars turned around and returned.

After another two minutes, probably because Yao Hall had finished asking his superiors, he said on the intercom: "The reception staff in Maduo County have been arranged, please Professor Shen must pay attention to safety." ”

At the same time, the open vehicle in front of Shen Qi's car cut to the leftmost lane to give way to Shen Qi's car.

Shen Qi was satisfied: "Thank you." ”

The convoy escorting Shen Qi all evacuated, and Shen Qi and their car galloped all the way towards Maduo.

Maduo is located in Guoluo Tibetan Autonomous Prefecture, with an average altitude of more than 4,000 meters.

Outside the county seat of Maduo stands a snow-capped mountain--- which is the source of the Yellow River, China's mother river.

Maduo County, in the headwaters of the Yellow River, is blessed with many natural resources, and the local people once proudly said: "Maduo is full of treasures, grass on the ground, fish in the water, and gold in the sand." ”

Grass is not ordinary grass, it is Cordyceps.

The fish is not an ordinary fish, it is a very valuable Yellow River naked carp.

Gold is the gold that everyone is familiar with, and the color and purity of the gold produced by Maduo are very famous throughout the country.

Rely on the mountains to eat the mountains, rely on the water to eat the water.

The abundant and precious natural resources of Tianci Maduo made Maduo the richest county in the province in the eighties of the last century.

However, only a dozen years later, by the end of the nineties, Maduo had changed from the richest county to a national-level poverty-stricken county.

What exactly did we do to Mado?

Clearly, the main causes of Mado's poverty are overgrazing, exploitation and fishing.

The scenery of this section of the journey from Xining to Maqin is charming and magnificent, and Shen Qi and his party are in high spirits.

Two graduate student volunteers took pictures with their mobile phones, and Shen Qi was also taking pictures.

Early in the morning, I stood in the green pasture and saw the eagle draped in the glow.

Like an auspicious cloud flying across the blue sky, it brings auspiciousness to the children of collectors.

......

This is a magical heavenly road, and the song is very realistic.

When he first entered Guoluo Tibetan Autonomous Prefecture, the sky was blue and washed his soul, and the snow-capped mountains stood proudly in the distance, and Shen Qi, who did not believe in religion, couldn't help but want to worship.

The pasture is endless, the green carpet is scattered with cattle and sheep, they eat and walk leisurely, the herdsmen ride horses and sing songs, the sky is vast, the wind blows the grass and sees the cattle and sheep.

"Picturesque. Shen Qi opened his laptop and enjoyed the scenery outside the car while accessing the data of the meteorological observation station in the Qinghai-Tibet Plateau region provided by the National Meteorological Center.

Combined with numerical analysis and mathematical model, Shen Qi calculates that the negative region of the third mode is concentrated in the southeast of the Tibetan Plateau, and the positive region appears in the northwest.

After passing Maqin, the vehicle turned and headed northwest, where it was destined for Maduo County.

Maduo County is larger than the capital and has a population of just over 10,000.

Entering the territory of Maduo, the style of painting has changed abruptly.

There are no longer rolling pastures, and there are more and more deserts.

The wind continued to blow, but the cattle and sheep were nowhere to be found, but a cloud of sand and dust was blown.

"Seeing is believing, desertification is very high here. Shen Qi frowned, his eyes looked at the yellow and green land outside the window, and his fingers quickly tapped on the keyboard of the notebook.
