The Liangshan Yi Autonomous Prefecture has the largest population of ethnic Yi people in China. Yi people came into Chinese and western history books as (Lolo) in the beginning. After the Chinese Communist Party came into power in mainland China, the government changed the name since the old name was widely regarded as derogatory. The appellations of Lolo, Lolopu, etc. are related to the Yi people's worship of the tiger, as "lo" in their dialects means "tiger." "Lo" was considered condescending, comparable to the Chinese name "a long-tailed ape." Languages reforms in the People's Republic of China replaced it to "net for catching birds." However, the stigma remained and resulted in negative remarks when people of the prefecture visited other cities. So the government changed the name of the prefecture.
