Lingyan is a giant panda, which lives in the mountainous area in the north-central Sichuan Basin, Sichuan Province, China. Because Lingyan is relatively fat, some individuals in the crowd are nicknamed "fat", and "fat rock" is one of them. In addition, this naming method also makes it easier for people to pay attention to these lovely giant pandas, so as to carry out more in-depth protection and research work.
