Original title: Take root in the front line and write youth answer sheet with persistence

In 2014, Shi Ruichuan, a junior at China Medical University, followed the school's association "Cradle of Red Medicine - People's Medical Corps from the Red Army" for the first time to enter Zhuanghe District, Dalian, Liaoning Province, to carry out early screening services for gastric cancer.

Zhuanghe area was once one of the high incidence areas of gastric cancer in China. At that time, Shi Ruichuan saw that the local medical technology conditions were backward and the villagers' awareness of cancer prevention was weak, so he had the idea of becoming a tumor doctor.

"The growth process of a medical student is long." Shi Ruichuan knew that the future career planning could not rely on "improvisation". Since she chose a path, she had to "go to the end", and her "go" was 10 years.

After making up his mind, Shi Ruichuan started to set up a disease management team to carry out medical services in the countryside. Over the past 10 years, Shi Ruichuan and his team have sent 68 groups of team members to complete 4296 gastric cancer screening, helping Zhuanghe area become a demonstration area for early cancer screening from a high incidence area of gastric cancer.

Shi Ruichuan, who graduated as a doctor in 2021, has grown into a specialist in cancer.

Like Shi Ruichuan, there are still many students who have taken root and fulfilled their commitments because of one opportunity. On the morning of June 12, representatives of young students from all over the country gathered at the national launching ceremony of the "Youth Red Dream Building Journey" activity of the China International University Student Innovation Competition (2024), with the theme of "My post is in the countryside, in the workshop, in the desert, in the deep sea, in the blue sky", sharing their own experience in basic medical care, intelligent manufacturing, green environment Innovation and entrepreneurship practice in sea and air equipment and other fields.

What is the reason why a native "southern potato" has taken root in the desert for six years? Nie Qixia, a doctoral student at Chongqing Jiaotong University, gave the answer "Keep the oasis and the people's homes".

In 2019, Nie Qixia, an undergraduate, followed her teacher to set foot in the Ulanbuhe Desert of Inner Mongolia for the first time. Before that, she "didn't have much concept" of desert.

"Since then, the desert has become my second home." Nie Qixia spent four or five months in the desert every year, withstanding yellow sand and scorching sun in the daytime and biting cold wind in the evening. All she did was to study the key technology of "desertification" and achieve "sand gathering into soil".

Under the harsh natural conditions, Nie Qixia also had the idea of giving up. But by chance, she and her brothers and sisters came to a village eroded by the desert. Because of the serious desertification, the villagers had to leave their hometown, and this became a "no man village".

Nie Qixia was touched. She decided to stick to it and protect it with what she learned. Through efforts, Nie Qixia's team has achieved success in more than 20 experimental sites at home and abroad, such as deserts, gobi, islands and reefs, and sandy grasslands, with a transformation area of 40000 mu.

"When I saw such large turnips, watermelon, tomato, pepper and other fruits and vegetables growing in the barren desert before, they could bring good benefits to the people in the desert area at the same time of ecological management. I think our work is worth it!" Nie Qixia said with a smile.

Nie Qixia has her own "small plan" for the future. She and her team calculated that even if only 1% of China's desertified land is transformed, more than 20 million mu of usable land will be added. "How meaningful that must be!" Nie Qixia sighed that although this goal was far away, she was willing to give the answer with persistence.

Some people insist in the desert, others insist in the deep sea.

"Listen, this is the sound from the deep sea." Zhang Xuanye, an undergraduate of Harbin Engineering University, played a 6-second recording at the launch ceremony, leading to a story from the deep sea.

The deep sea is the largest unknown area of the earth. In order to realize the dream of "catching turtles in the five seas", acoustic release is indispensable. Like the code lock on deep-sea equipment, it is the key to ensure long-term deployment and safe recovery of deep-sea equipment.

In February 2024, Zhang Xuanye and 17 members of the scientific research team boarded a scientific research ship heading for the Western Pacific Ocean to deploy a domestic deep-sea acoustic release device in the 7000 meter deep sea.

During the voyage, they never backed down from the tests of seasickness, typhoon, huge waves and so on, and always stuck to their experimental posts.

At 4:00 a.m. on March 25, the scientific research ship arrived at the predetermined point and was ready to recycle the seabed equipment. Zhang Xuanye nervously pressed the signal transmission button. It only takes more than ten seconds for the acoustic signal to be transmitted to the deep sea, and then transmitted back to the water surface after being fed back by the releaser. However, this short ten seconds has condensed countless efforts.

"The scientific research team members on the same ship often ask me 'whether the performance of domestic equipment will work in the end', and each time I firmly say 'no problem'." Although I say this, Zhang Xuanye's heart will also be nervous.

At this time, Zhang Xuanye heard a beautiful voice. This is the signal echo from the deep sea, representing the successful "unlocking" of the domestic acoustic release device in the deep sea.

"When the five-star red flag on the acoustic releaser surfaced, the whole ship shouted with excitement." Zhang Xuanye smiled and said that he was extremely proud of his persistence and dedication in the deep-sea post.

As the "Qian Xuesen Digital Man" generated by AI technology at the launch ceremony said, "there are no young people who do not stumble and meet a few obstacles", but "do not lose confidence, as long as you persevere, there will be results".
