Residency, is most fundamental and immediate concern to everyone. But The house prices remain high, so that "living" become a luxurious dream. "Justice of Inhabitation rights " becomes a big issue, and there have been heated debates on the it.

The society in Taiwan tends to be heterogeneous. On the impact of the economic growth, many aborigines migrated from homeland to urban area for working. Because of the different culture and lifestyle, their migration brought about a phenomenon called “aborigines dwelling in cities”, and the first problem they faced was "where to live?". The object of this thesis(in depth reporting) "Sanying tribe" is considered to be unapproved construction project beside the river, and it has been being ordered to demolish since 1990. As a result, their life have been going from bad to worse. Then, they organized a self-help organization to protest themselves, and they have been getting a lot of public support for years.

For solving the inhabitation problem, the government promote the Social Housing Policy , which emphasize that "rent it, not buy it", trying to reduce the cost of living. After a long-term resist, the Sanying tribe win a chance of the reconstruction plan, which is based on "Social Housing" , trying to re-build a "New Homeland" in city.

This reports tried to find the answers for the following questions:
1. What the differences between the former relocation due to demolition, which called ''Public Housing of Sanxia, street Long En Bu" and the present reconstruction plan?
2. What will be the result of the combination of the "Social Housing" and " Aboriginal Tribe Reconstruction"? Does this new reconstruction plan meet the needs of the residents, especially for their cultural needs? How does this plan avoid doing the same defects as the other tribes reconstruction plan?

After interviews and researches, I found that there are so many difficulties over this tribe reconstruction plan, and the worse is there isn''t any precedent case to follow. These difficulties include: How to rent the state-owned land? Will the rent be a hard burden to the residents? Will the cooperation between government and the Sanying tribe work?

Face all these obstacles, Sanying tribe equip themselves with a complete organizational structure, with the helps from the Organization of Urban Re-s (OURs) and the Social Movement Organizations. They have been dealing with National laws and regulations , tribe reconstruction plan and the actual situation. Sanying tribe will be a "Nonprofit Corporation" to rent state-owned land, and then do the self-build housing, which is considered to be another measure for completing "Social Housing Policy" , especially to meet different cultural needs.
