Yungdrung Dakyi, a Tibetan worker, is the winner of the national "Labor Medal" award, one of the highest honor for the working class in China. He and his squad once worked continuously for nearly 20 hours a day to maintain roads at a high altitude of 4,830 meters. Countless workers like him have been working hard to build and maintain heavenly roads in Tibet to make local people's lives more convenient. CGTN reporter Yang Xinmeng greets him by the roadside that he is working on and listens to his stories.
