Dot blue words to follow "CCTV News"
In the "Poems" chapter of the 2021 hit movie "My Father and Me", Master Yu, played by Zhang Ziyi, is a gunpowder sculptor in the space system. In the film, a detail is impressive: Master Yu's assistant accidentally touched the tool on the table when taking something, and when the tool fell into contact with the residual medicine, it instantly caused an explosion and burst into flames...
This is the gunpowder carver— a profession that deals with danger at all times but is indispensable.
One of the prototypes of "Master Yu" in the movie story is Xu Liping, a big country craftsman.
"Every time you drop the knife, you can hear your own heartbeat. You can't make a difference in the slightest bit of gunpowder, and every weapon of a big country can't be separated from you. You are a craftsman, you are a craftsman of a great power. This is the award speech exclusively for Xu Liping at the 2015 "Moving China" ceremony.
He worked "in the explosive pile" for more than 30 years
But I never thought about leaving
Xu Liping is the leader of the solid fuel drug surface shaping group of the aerospace engine of the 7416 factory of the Fourth Research Institute of China Aerospace Science and Technology Corporation. He has been working in what he calls "in the explosive pile" for more than three decades.
Xu Liping clearly remembers the first lesson given to him by the teacher Fu when he first entered the factory at the age of 19, "At that time, the master took me to deal with the waste medicine block, pop, a little fire, followed by a huge roar, a dazzling fire, a mushroom cloud in the air, even if standing more than ten meters away, the heat wave that swept in was still unbearable." ”
This class left a deep memory for him. It was also from then on that Xu Liping understood that if he wanted to avoid danger, he could only be bold and careful and practice the knife in his hand.
"So dangerous, have you thought about changing jobs?" The answer given by Xu Liping is: "No matter how dangerous the work, someone must do it, and why am I not that person?" ”
0.5 mm, is the maximum error allowed by the accuracy of the solid engine surface. Nowadays, Xu Liping has already practiced a unique skill, and the engraving accuracy can reach within 0.2 mm. "Whenever I see the Long March rocket and the Shenzhou series of spacecraft going straight up into the sky, the pride and excitement in my heart cannot be replaced by any honor."
Participate in the Shenzhou series escape tower medicine surface micro-plastic surgery
"Most wish I threw it away every time"
In 2021, the mainland Shenzhou XII and Shenzhou XIII manned spacecraft were successfully launched. Xu Liping's team participated in the micro-shaping of the solid fuel surface of the escape system.
The escape tower of the Shenzhou series has always been known as the tower of life for astronauts, and once an accident occurs, it can help astronauts get out of danger. Xu Liping introduced, "Because it is related to the safety of astronauts, it has higher product quality requirements than other products, and the operation process will be more meticulous." The quality of this product must be absolutely reliable. ”
When God TWELVE and God Thirteen were launched, Xu Liping bluntly said that "the heart is hanging", "I am afraid that the escape tower will play a role, because once it plays a role, it will be a bit of a problem to launch." But if you really need to use the Escape Tower, I hope it must be foolproof. But what I want most is to throw it away every time. ”
It was not until the commander of the instruction ordered the escape tower to be thrown away that Xu Liping's hanging heart would be put down, "because at that time, it showed that the launch had basically been successful."

When carving, use the mentality of ensuring that there is no mistake to carve; after the rocket is launched, I hope that what I do will never be used, which is the inner portrayal of Xu Liping and the team colleagues. "Obscurity is actually the working state of our entire space system. It is the joint efforts of all astronauts that have created so many space miracles. ”
Generations of astronauts have continued to pass on the legacy
Write the most beautiful poem about the universe
In order to ensure safety, Xu Liping also designed, made and improved 30 kinds of knives, of which 9 kinds of knives applied for national patents, and one tool was named "Li Ping Knife" by the unit.
Now, a major focus of Xu Liping's work is to cultivate young people and let them grow up quickly. "Now our team has more than a dozen post-90s."
Over the years, Xu Liping has brought out many apprentices, and the apprentices have their own apprentices, and the spirit of aerospace has been passed down from generation to generation.
In the new year, Xu Liping hopes that the aerospace industry of the motherland will continue to develop rapidly, and he also hopes that the epidemic will pass as soon as possible, and he will accompany his parents out for a turn.
At the end of the poem chapter of "My Father and Me", a poem written by the parents of astronauts to their children has brought countless people to tears: "Fuel is, igniting oneself, illuminating other people's things; rockets are things that abandon themselves for dreams; life is, for burning things; death is, something that verifies life; the universe is something that makes death small..."
In the flying dream of asking the heavens, there are countless "Xu Liping". With silent perseverance and hard work, they wrote a romantic poem about the universe.
