As a student of Huanong, I think Huanong Yogurt is superior to those commonly found in shopping malls, and Huanong Yogurt is only sold in colleges and universities because Huanong Yogurt Factory is a state-owned enterprise, a subsidiary of South China Agricultural University Science and Technology Development Company and a school-run enterprise, and does not need to join any fierce social competition. It can win by quality if necessary.
At present, Huanong Yogurt is in Huanong, as well as several nearby universities, such as South China Normal University and South China University of Technology, as well as some shops around the school and a university town. There are not many other estimates.
