《新唐书·列传·卷一百四十七》
柳不能做主而还，蛮人以三百骑兵运了幄幕来，说以供敷张隋蜀王的用事厅，是我们骠信的行宫。
槃未能决，还。蛮以三百骑负幄幕来，大言曰： 供帐隋蜀王听事，为骠信行在。 
Liu could not make the decision and refused, but the barbarians sent over 300 cavalrymen along with tents which they said were for the Sui/Shu king to hold court and were being used by our general as an imperial headquarters.
