In Chengchuan town of Ordos in the Inner Mongolia autonomous region, the Yang Zao and Han Chun Memorial Hall, established in 2017, tells the story of an American couple who worked to help improve the lives of people in the region in the 1940s.
The hall uses the Chinese names of Erwin Engst — an agricultural and livestock breeding expert — and his wife, Joan Hinton (Yang and Han). It covers an area of 26,000 square meters.
