During the Spring Festival of 2018, a car with four people started from Jingzhou, passed through Guilin, and headed west from the border of Guangxi to Honghe Prefecture in Yunnan. We left the expressway in Wenshan, the hometown of Panax notoginseng, and after many twists and turns, we found a path along the mountains and cliffs, and passed through the thrilling journey to the famous Yunnan-Vietnam Railway project in the deep mountains and old forests of Wujiazhai, Pingbian County - the Herringbone Bridge. Under modern traffic conditions, it is so difficult to reach the Herringbone Bridge. It is conceivable that it was difficult to participate in railway construction a hundred years ago. The courage of the Chinese is commendable, and the engineering design of the French is also remarkable.

We parked the car near the old station of the Yunnan-Vietnam Railway and walked a section of the Yunnan-Vietnam Railway: from the tunnel at one end of the herringbone bridge, we walked in the dark to the herringbone bridge.
In the absence of modern engineering conditions, the tunnel excavated by Chinese workers through semi-manual work under the guidance of French engineers has been operating safely for more than 100 years. The dark tunnel was very quiet, and time seemed to have stopped a hundred years ago. The lives of nearly a thousand workers marked the tunnels and bridges with fresh life. Step on the ballast and walk slowly along the railway track towards the bright light at the entrance of the tunnel. Slowly, you can see the swaying figures of tourists in twos and threes, as if they have been transported from a hundred years ago to modern society.

The initial impression of Bisezhai came from the novel "Bisezhai" written by Fan Wen, a Tibetan writer. The book describes positively the French and Chinese living together as equals, using French technical advantages and Chinese human resources to build the first railway in Yunnan, transforming Yunnan in mainland China into a port for foreign development on land in China. Coupled with the Western religious culture brought by missionaries, the cultural accomplishment of Yunnan, a land of southern barbarians, has skyrocketed, confirming the principle that foreign exchanges produce wealth and civilization.

Information: The Yunnan-Vietnam Railway is the first railway in the history of Yunnan and also the first railway in my country leading to foreign countries. The Herringbone Bridge was designed by French female engineer Bauer-Baudin. Construction started on March 10, 1907 and was completed on December 6, 1908, which lasted one year and seven months. The herringbone bridge is constructed of more than 20,000 sets of rivets, with the largest component less than 2.5 meters. They were all made in France and then shipped to Yunnan. When riveting bridge components, it is even more thrilling. The arch arms are suspended in mid-air in the valley. This kind of work is so life-threatening that the French have to give the stimulation of "half an ocean for every hammer blow". Here, life seems to be It is so fragile that the construction of the herringbone bridge cost more than 800 lives. This has never happened in the history of bridge construction in the world. The grid-shaped trusses and herringbone arches on the herringbone bridge are integrated and fly across the cliffs of the two mountains. The construction concept of the herringbone bridge is the same as that of the Eiffel Tower in France. It is a masterpiece in the history of railway bridges in the world. It is also known as the world's three major projects along with the Panama Canal and the Suez Canal. This light and strong bridge is listed in the "World Famous Bridge History".
