They were found side by side close to the walls of the houses at the site, implying that people of the time customarily buried their dead in their homes. It is believed to be a coincidence that aborigines who later settled in Taiwan also buried their dead under their homes.
這些石棺很密集，隔一、二公尺就有一個，而與附近發現石壁的住宅區，也只有數尺之隔，有的石棺甚至在石牆下，初步推測當時有內葬習俗，就是將屍體葬在屋內，而台灣山胞早期也曾經有葬在床底下的風俗。
