Liu's opinion as an archaeologist is that when the school is rebuilt, all construction should be banned from the southern part of the campus, where the prehistoric site is best preserved. Meanwhile, construction on the northern part should only proceed after it has been explored and evaluated by archaeologists.
劉益昌建議：整個大龍國小改建時，南邊遺址保存很好的區塊不准建設，而北邊區域要建設前則必須進行考古探勘評估。
