《左传·襄公·襄公十八年》
我即位后，到现在五年，军队不出动，人们恐怕认为我只顾自己安逸而忘了先君的霸业了。
不穀即位，于今五年，师徒不出，人其以不穀为自逸，而忘先君之业矣。
Since my enthronement until this date, it has been five years, and the army has not taken action. People are probably thinking that I am only concerned about my own comfort and have forgotten my ancestors’ accomplishments.”
