The Ly/Lyfoung was supporters of the French colonialists and the Lo/Lobliayao, of the Japanese invaders: the end of the World War II divided the Hmong community into two fractions.

Faydang Lobliayao (Faiv Ntaj Lauj Npliaj Yob)
Faydang Lobliayao was a politician in Laos who was the son of Kiatong Lobliayao (Kiabtoom Lauj Npliaj Yob). He felt that the leadership position of Tasseng (Tojxeem) should be passed from his father to him; but instead it was passed to Lyfoung and down to Touby Lyfoung. He petitioned the colonial French government for the position but was denied. He and his fellow clansmen aided the Japanese in their occupation of Indochina. As late as 1947, he made contact with the Lao Issara, most notably Prince Souphanouvong. He became Vice-President of the Neo Lao Hak Sat, though his power is more ceremonial than real.
