《梁书·列传·卷四十三》
说完立即骑马奔出，部署军队准备出发，正好江州刺史当阳公萧大心派使者来邀请韦粲，韦粲就骑马去拜见萧大心说： 长江上游各个藩镇，衹有江蛆离京城最近，从殿下的情况考虑，实在应当先去救援；但是中游地位重要，你驻守江州任务重大，其他人救援京城也需你们接应，逭裹不能无人镇守。
即驰马出，部分将发，会江州刺史当阳公大心遣使要粲，粲乃驰往见大心曰： 上游蕃镇，江州去京最近，殿下情计，实宜在前；但中流任重，当须应接，不可阙镇。
After he said so, he immediately rode out and deployed troops to prepare for departure. It happened that the Jiangzhou governor, Xiao Daxin, the Duke of Dangyang, sent an envoy to invite Wei can. Wei can rode out to meet Xiao Daxin and said: Among the various vassal towns in the upper reaches of the Yangtze River, only Jiangzhou is closest to the capital. In terms of Your Highness's situation, you should really go to the rescue first. However, the middle reaches are of great importance. You have the important task of guarding Jiangzhou. Others who go to the rescue of the capital need your support, and Jiangzhou cannot be left undefended.
