This is a 20-year-old ranch located in Anhui Province, China. The owner of the ranch is Mr. He, a customer who has cooperated with us for fifteen years. Our cooperation started with the circulation fan. Mr. He was amazed at the quality and efficiency of the fan, "Originally, I only needed a fan with a large air volume. I didn't expect its noise to be so small. It is very power-efficient to use. After installation, it basically requires no maintenance." Next, Mr. He also replaced the free stall of the ranch iron. It has become the plastic free-stall of Terrui, the plastic free stall is more comfortable, the comfortable cows are healthier, and the milk production is higher. Now, Mr. He has become our loyal fan, and every new product of Terrui will invite Mr. He Try it out, Mr. He will also give us feedback and suggestions, Terrui is willing to grow together with every customer.
