Liangmei community has a good repo for claiming land that does not belongs to them. The Meremei incident is a case in point and as result, the chief is extremely hesitant to allowed them to settled in his land despite being from the same community. So, it is highly unlikely that the Leilon Kuki would accept & permit the Liangmei family to construct a house on their land.

Note: The video in circulation does not depict a Kuki-Liangmei conflict but rather an internal dispute between members of the Liangmei community itself!
