The automatic train hook invented by Jenny is basically the same as the automatic train hook used now. Jenny invented the train hook and wrote "Jenny" in English.
CoupIer. The catalogue of early railway materials in China is simply translated as "Zhan's coupler". Because Zhan Tianyou was the most famous railway engineer in China in his early years, some people mistakenly thought that the automatic train hook was invented by Zhan Tianyou. For example, in the book "Railway between Zhan Tianyou and China" co-authored by Xu Qiheng and Li Xi published by Shanghai People's Publishing House, there is a photo of automatic train hook entitled "Automatic train hook in Zhan Tianyou".
It is said that Zhan Tianyou had heard of this misinformation before his death. He sincerely said to the people around him: "Please help me explain, there is no such thing." Later, Zhan Tianyou compiled a new Chinese-English vocabulary of engineering, including the word "Janus coupler". In transliteration, Zhan Tianyou deliberately changed the word "Zhan" to "Zheng" and translated it into "Zheng's coupler".
The difference between this word and spirit. It shows Zhan Tianyou's noble character of seriousness, integrity and not robbing others of beauty.
