《汉书·传·楚元王传》
到迁徙昌陵，把低处填高，堆积土成山，打开百姓的坟墓，总共数以万计，修建城邑，时间紧迫，耗资一亿零几百。
及徙昌陵，增埤为高，积土为山，发民坟墓，积以万数，营起邑居，期日迫卒，功费大万百余。
When you moved to Chang Mausoleum, the low places were filled in, piled earth into a mountain, opened up people's graves, in all by the tens of thousands, and building the cities, it was rushed, and cost over a hundred million dollars.
