The Limi are one of more than 100 groups in Yunnan who have been combined into the official Yi nationality by the Chinese authorities. The Limi were first documented by China Inland Mission's John Kuhn in the 1940s. In his benchmark book, We Found a Hundred Tribes, Kuhn listed the Limi as a Lolo-speaking group located at "Qingku." Qingku is the pre-1949 spelling of today's Jinggu County in Simao Prefecture.

The Limi claim that their ancestors came from a place called Dayuandi in Jingdong County long ago. They reportedly were slaves of a tyrannical master. One day the Limi escaped en masse and won their freedom. They moved to their present locations where they settled down and started new communities.

Compared to other Yi groups in the area, such as the Western Gaisu and some of the Laluo, the Limi culture has been well preserved. Until recently the Limi strictly refused to intermarry with the Han Chinese or even with other Yi groups. Because of this, they have gained a reputation for being something of an isolated, inward-looking group who have little contact with other people. The Limi joyously celebrate several festivals throughout the course of the year.

Polytheism, animism, and ancestor worship prevail among the Limi. Regular ceremonies are held to worship the spirits and honor their ancestors.

The independent mind-set of the Limi has contributed to them being unreached and largely unevangelized today. Few missionaries worked in the area prior to the expulsion of foreigners from China in the 1950s. If the Limi had been so fortunate to have workers like Gladys Aylward focusing on them, they would have been greatly blessed. Aylward described the hardship she faced daily in China: "Life is pitiful, death so familiar, suffering and pain so common, yet I would not be anywhere else. Do not wish me out of this, or in any way seek to get me out, for I will not be got out while this trial is on. These are my people, God has given them to me, and I will live or die with them for Him and His glory."
