《宋书·志·卷三十一》
造以前，自置迁都红南之后，各种礼仪制度多有缺漏，耋迭壶建立明堂，打造皇帝专用的玉辂、金辂、象辖、革辖、木辂等五种辖车。
先是江左以来，制度多阙，孝武帝立明堂，造五辂。
Before the construction, there were many deficiencies in various ritual systems after the relocation of the capital to the south. Emperor Di Dao established a bright hall, and built five carriages for the emperor's exclusive use, namely jade carriage, golden carriage, elephant carriage, leather carriage and wooden carriage.
