It's just unfortunate that no interdisciplinary study of facial tattoos was carried out in years past. A lack of pictures for future research and analysis is particularly vexing. Frustratingly, all one can do is sit and watch as respected tribal elders pass away one after another.
只是，以往並沒有針對文面文化做全面性的研究和調查，尤其缺乏影像資料可以考據，供日後分析研究，如今坐視耆老一一過逝，實在令人惋惜。
