《左传·昭公·昭公七年》
如果君王不来，使臣请问君王带兵出动的日期，寡君将要捧着进见的财币，而到蜀地去见君王，以请问鲁先君成公的恩赐。 
君若不来，使臣请问行期，寡君将承质币而见于蜀，以请先君之贶。 
If the king doesn't come, the envoys should ask the king when he will send troops, and the king will hold the presented treasure and go to Shu to see the king and ask about the kindness of King Cheng, the former sage of Lu.
