中国最悲壮的工程奇迹：800人殒命建成【4K】

A world engineering marvel on the Yunnan–Vietnam Railway: the Renzi Bridge (human-shaped bridge) The Yunnan–Vietnam Railway, completed in 1910, is a miracle in railway construction history, and the Wujiazhai Renzi Bridge is its brightest and most tragic jewel. More than ten thousand steel connections and over two hundred thousand rivets were hammered into the structure one by one. The bridge was designed by French engineer Paul Bodin and built in 1908. The name “Renzi Bridge” comes from its unique structure. It has no pillars — two massive steel arms form the character “人” and support themselves on cliffs. It is nearly 70 meters long and weighs about 170 tons. But its construction was tragic. Tens of thousands of workers worked without cranes or safety equipment, hanging at nearly 200 meters above the ground. Over 800 Chinese workers died here. 📍 Location: Wujiazhai 📍 Yunnan, Pingbian 📅 July 20, 2025 ⛅ Weather: 30°C 🎬 CHAPTERS 00:00 Preview 00:48 Canyon entrance 04:22 Viewpoint 10:00 Shelter cave 14:17 Tunnel 16:42 Bridge close view 28:50 Train passing 29:36 Lonely station
