Tauhi vā is a very important concept in Tongan and Pacific culture,which refers to the maintaining,sustaining or nur-turing of social relations.By fulfilling their responsibilities(fai fatongia),people build harmonious and good social relations.This concept profoundly influences every aspect of the daily life of Tongans and shapes the way Tongans think and behave.In recent years,however,people gradually deviate from the original intention in the process of tauhi vā,resulting in disharmony or asymme-try.While changing the current mindset,Tongans are also actively exploring new ways of tauhi vā with a view to achieving a virtu-ous cycle and sustainable development of tauhi vā.
