1905- 1909 In order to develop commerce, the Qing government decided to build the Beijing-Zhangjiakou Railway. Zhan Tianyou was assigned to be responsible for road construction, first as chief engineer and general manager, then as general manager and chief engineer. This road runs from Beijing to Zhangjiakou and across the Du Jun Mountains. The terrain is steep and the project is extremely arduous. It is about 200 kilometers long and is the main road leading to the northwest. In order to compete for the right to build roads, Britain and Russia were deadlocked, and the Qing government decided to build it by itself, but it lacked confidence. Foreigners are talking about China's inability to complete the road construction project. Zhan Tianyou said: "China has a vast territory and rich resources. It is shameful to rely on outsiders for all the work along the way!" In the face of foreigners' sarcasm, he led all road builders to face difficulties with fearless spirit. Qi Xin won glory for his country.

19 19 at the end of the first European war, Zhan Tianyou attended the International Conference on Far East Railway on behalf of the China Institution of Engineers, braved the cold and rushed to the conference site to argue with the Japanese representative who tried to occupy the Northeast Middle East Railway in China, and obtained China's right to protect the Middle East Railway.
