Who are the Lolo?  The Lolo people make up one of  Vietnam’s 53 minority groups with an estimated  population of 3,900.  They are not only a small group, they are also considered somewhat mysterious.  Pronunciation : "Loh-loh"

They are known by a number of other names.  Of these, Yi, or O Man are perhaps the most common, but they are also known as: Mun Di, Di, Man Di, La La, Qua La, Pen Ti Lolo, and Lu Loc Man.

The Lolo may be the same as the Pu tribe (population 65,000) who live in adjacent areas in China. The Pu are officially  included under the Yi nationality by the Chinese government, which contains more than 90 loosely-related tribes and sub-groups speaking more than 30 distinct languages.

They are a completely unreached people group.
