The 48th WorldSkills Competition was held in Shanghai, and the four major invention themes of the China Pavilion became the focus

China News Service, Shanghai, September 24 (Yang Shuo) On the 24th, the 48th World Skills Competition (hereinafter referred to as the "World Competition") was held in Shanghai. This World Championship adopts the "one competition and two conferences" model, holding the WorldSkills Conference and the WorldSkills Expo (hereinafter referred to as the "Expo") simultaneously. The China Pavilion in the expo became the focus of attention.

"The China Pavilion uses the beams of Chinese classical architecture as the overall shape, highlighting the theme of 'pillars and beams'." Zheng Yixin, the chief planner of the expo, said that the pavilion adopts a four-sided opening layout, and the four directions correspond to the four great inventions of ancient times. The main colors are fire red, movable type gold, Sinan green, and paper rhyme white.

In the gunpowder exhibition area, the story of aerospace technician Xu Liping is particularly eye-catching on the exhibition wall. He is engaged in precision repair of rocket powder surfaces, and the error is controlled within 0.2 mm. The display cabinet displays a series of knives patented by his team. This skill cannot be replaced by machines. Equally eye-catching is nuclear industry technician He Shaohua, who can complete blind repairs of reactor cores in a high-radiation environment. He uses original techniques to add protective sleeves and production channels to the heavy water reactor core, creating key conditions for the production of short-cycle medical isotopes.

"The exhibits in the compass exhibition area are all real objects of great powers, not models." According to the commentator of the China Pavilion, the actual return capsules of the returnable satellites of the last century are placed there. The dense cable network in the cabin is called "the blood vessels and nerves of the spacecraft." The exhibition wall tells the story of Hao Chunyu, a radio assembly worker who has been involved in the precision assembly of aerospace cable networks for more than 30 years and achieved nearly ten million solder joints in orbit with zero faults. Beidou navigation is not only in space, but also in the fields. At the end of the exhibition area, agricultural machinery equipped with the Beidou autonomous driving system is displayed, which has transformed from a hand-held plow to a human viewing screen. There are 2.66 million smart agricultural machinery across the country connected into a network.

Papermaking technology extends from flat paper to electronic media, completing the transformation of carriers. Today, printing technology is even richer. Movable type printing enables flexible typesetting and batch copying of text. Printing operators and gravure printers directly inherit this logic, and a new position of "additive manufacturing equipment operator" has been born, corresponding to 3D printing technology. "3D printing continues the logic of stacking layer by layer and forming on demand. This is an innovative application of movable type printing in the field of three-dimensional manufacturing." The commentator introduced.

"We want to use the wisdom of China's ancient civilization, coupled with China's current skills development, to make a comparison between ancient and modern times to reflect the contribution and role of China's skilled talents in the entire development process." Zheng Yixin said. From the four great inventions to Beidou navigation, the narrative of skills spanning thousands of years completes the dialogue in 800 square meters.
