走進中國麻將工廠，看一副麻將如何誕生

A simple-looking Mahjong tile actually goes through many complicated manufacturing processes before it reaches the table. In this episode, we visit a Mahjong factory in China and record the complete production process — from molding the tiles, installing magnets and internal weights, polishing, sorting, coloring, hand cleaning, inspection, and final packaging. Many people play Mahjong every day, but few know that magnetic components and special structures are hidden inside each tile. Every piece needs to go through multiple steps before becoming a finished Mahjong set. This video has no narration. We keep the original factory sounds and show the real atmosphere of Chinese manufacturing. 00:00 Start of Mahjong production 00:45 Molding Mahjong tiles 03:50 Installing magnets and adding internal weights 04:50 Sorting and polishing process 06:20 Coloring process 07:30 Automatic coloring machine 08:30 Workers manually cleaning excess color 10:00 Final inspection and packaging Thank you for watching.
