In May 2006, Dong He, a young farmer from Nanwangzhuang Village in Guli Town, Xintai City, Shandong Province, came up with an innovative idea to create a milking machine using the vacuum negative pressure principle. His invention quickly gained popularity among local farmers. Before this, manual milking was not only physically demanding but also led to issues like poor milk quality and damage to the cow's teats. Dong’s machine solved these problems effectively. Today, his invention has earned three national patents and has been selected as a science and technology SME innovation fund project by the Ministry of Science and Technology. The product is now sold across more than 10 provinces, including Jilin and Inner Mongolia, generating annual sales of over 2 million yuan. The image shows Dong He working alongside Silver during the assembly process of the milking machine. His story is a great example of how simple ideas, when properly developed, can make a real difference in agriculture and rural life.
