God bless the coupler-invented by Zhan Tianyou.

Zhan Tianyou, the father of Chinese railways.

Zhan Tianyou, the word as soon as possible, Wuyuan Lu cheat people. The earliest outstanding railway engineering expert in China. Yu Qing Xianfeng was born in Nanhai County, Guangdong Province on March 17th, 11th (great-grandfather Zhan Wanbang was born in Guangdong, and you Zhan Hongxing worked as a farmer in Nanhai). I went to a private school when I was a child. At the age of twelve, he was selected by the Qing government as the first group of young children to study in the United States. After graduating from primary school and middle school, he was admitted to the Civil Engineering Department of Yale University to study railway engineering, and graduated from the university at the age of 2/kloc-0 with a bachelor's degree. After returning home, he was sent to be a soldier's pilot. He took part in the Sino-French Mawei naval battle and fought bravely against the French invaders. In the twelfth year of Guangxu, he worked as a foreign language teacher and charting in the erudite museum. In the 14th year of Guangxu, he served as an engineer of China Railway Corporation and was elected as a member of British Engineering Research Association. Since then, he has successively served as the railway engineer of Jinyu, Jinzhou and Pingyi, the chief engineer of Xinyi Railway, the general manager and chief engineer of Jingzhang Railway, and the chief engineer of Luotong Railway Consultant. Xuan Tongyuan, a scholar in engineering, was appointed as the examiner of foreign students, consultant of the postal department and consultant of the department, and was sent to Yichang as the chief engineer of Shangchuan Railway. In the first year of the Republic of China, he served as the office of Guangdong-Han Railway Association and was elected as the president of China Institution of Engineers. In the third year of the Republic of China, he was appointed as Guangdong Hanchuan Road Supervisor, and President Sun Yat-sen promoted him to Dr. Shao Qing, appointed as the Minister of Communications, and awarded the second-class Baoguang Golden Harvest Chapter. In the eighth year of the Republic of China, he was sent to Harbin by the Beiyang warlord government to serve as the representative of the Far East Railway Conference supervised by the Allies and the Chinese representative of the Conference Technology Department. On April/0/5, 2008, he returned to Wuhan due to illness and died on the 24th at the age of 59. Zhan Tianyou's life has made outstanding contributions to the railway industry in China.

Engineers from Britain, Japan and France didn't pile when the Luan River Railway Bridge of the Jin-Yu Railway was built. Zhan Tianyou adopted China Weitong method with machine piling, which was successful. Xinyi Railway is the beginning of China engineering railway. Zhan Tianyou was completed in four months, two months ahead of schedule, which was appreciated by Empress Dowager Cixi and Yuan Shikai. The Beijing-Zhangjiakou Railway was decided to be built by China because Britain and Russia were at loggerheads over the right to build roads. Foreigners scoff at China's "overreaching" and "audacity", and Zhan Tianyou is determined to win honor for the country, carefully plan and construct. When digging Juyongguan and Badaling tunnels, Zhan Tianyou creatively adopted the construction method of digging at both ends and opening a shaft in the middle, without the difficulty of opening a new mountain knife, water pump and ventilator, and successfully solved the problem. For Badaling with steep terrain and steep slope, a "man" route is designed to make the train run smoothly. When driving, the cars were disconnected, and an automatic hook was copied, called "God Blessed Hook". The railway is planned to be completed in 6 years and 4 years, saving investment of more than 282,000 silver. It was regarded as a miracle by foreign engineers at that time.
