在山东博物馆新馆《山东历史文化展——秦汉一明清》展厅里,陈列着1956年出土于山东省梁山县宋金故河道林姊河内的一艘明代大船。它看起来比较陈旧,可它是京杭大运河出土古船中年代用途最明确、保存最完整的明代漕船,距今有600多年的历史。%In the hall exhibiting the Chinese historic culture from the Q in and ,Han Dynasties to the Ming and QjngDynasties, there stands a large boat of the Ming Dynasty unearthed from the ancient course of Songjin River in Liangshan County, Shandong Province in 1956. It looks old. However, among the ancient boats unearthed from the Beijing-Hangzhou Grand Canal, it is a boat for carrying grain to the capital of the Ming Dynasty with the most obvious function and is also the most complete, though it can be dated back more than 600 years.
