"Archaeological sites in Taiwan have flaked tools like these from the paleolithic to the late neolithic eras," notes Liu. From the standards of craftsmanship in their jade and decorative jewelry, it is clear that these people of ancient times were not without skill. However, it appears that as far as implements for daily use are concerned, their attitude may well have been "it's enough if it's usable."
「台灣遺址裡，這些打磨器具從舊石器時代用到新石器晚期」，劉益昌說，從玉的製造、裝飾等工藝水準看來，似乎遠古人類並非沒有製造技術，但對於生活器具用品卻未精琢細磨，也許是認為「可用就好了！」
