Aerial photo taken on Sept. 21, 2019 shows a livestock trading market in the suburb of Ar Horqin Banner, north China's Inner Mongolia Autonomous Region. The middle of September is considered by Inner Mongolia's sheep herders as a livestock trading season. "We can expect a rise in this year's live sheep market," says Yao Hui, a local sheep herder, who has also been busy finding buyers willing to pay a good price for his sheep. (Xinhua/Liu Lei)
