Very good video,where is it?this marginal tribe limbu ( exists 4 lakh +) can preserve their identity and existence by prioritising racial marriage.If people of limbu tribe cannot ban interracial marriages,this marginal people will merge into the species of madhesi bahun chhetri dalit in Nepal quickly. Limbu people will disappear in Nepal from 10 to 20 years.The hybridisation numbers of limbu people shows this bitter truth.
