The 48th WorldSkills Competition will take place in China from September 22nd to 27th. The competition tests practical skills in areas such as manufacturing and construction, with the goal of promoting technical and vocational education. One event is tiling, and members of China's team are undergoing intensive training ahead of the games. Competitors have four days and 22 hours to build walls and lay tiles based on drawings. The competition's concrete event requires competitors to use raw materials to build a full-scale structure within 22 hours. China's coaching staff designed a high wall with clover-shaped openings to test team members. The margin of error for key measurements must be kept within 1 millimeter.

GAO YANTAO, Technical Expert for Team China, Tiling 48th WorldSkills Competition "For example, the completeness and smoothness of the cuts are part of the subjective scoring. Next, I'll show you how judges check the vertical alignment during the inspection. For the test event, we require zero error. When the level is placed against the surface and the reading is zero, that means a perfect score. If it shows one, the corresponding points will be deducted."

YAO WANGZE, Competitor, Concrete Construction 48th WorldSkills Competition "For example, if the design calls for 200 millimeters, we need to cut the side panel to around 198 millimeters and then attach a sponge strip. To prevent concrete from leaking after it is poured, we need to leave room for the thickness of the sponge strip. These are all details that need to be considered very carefully. At the competition, everyone is at about the same level, so it's the small details that make the difference."
