“铺路石”精神是云南公路养护行业精神，是万里国道、数千里边防线上数万名养路职工的传统“家风”。几十年来，我们的养路职工不畏惧自然环境的恶劣，不惧怕高山峡谷的险阻，不计较物质文化生活的艰苦，无论是小修保养，还是大中修工程，无论是千里国防公路的保通，还是边疆? The spirit of “paving stones” is the spirit of the road maintenance industry in Yunnan and is the traditional “home style” of tens of thousands of road maintenance workers in thousands of miles of national defense and tens of thousands of miles of border line. For decades, our road maintenance workers are not afraid of the harshness of their natural environment and are not afraid of the dangers of alpine valleys. They do not care about the hardship of material and cultural life. Whether it is minor maintenance or large and medium-sized repair projects, Or border?
