This set phrase is derived1 Ji An made to the emperor.
Ji Anlived at the time of Emperor Wudi of the Western Han Dynasty and for daring to speak the truth. He did not bother about amall matters in personal behaviour and in being an official. He was particular about actual effects and ， a stir ， of this. the imperial court transferred him to th in charge of the appointment and dismissal of the local officals.
Once，Emperor Wudi said that he would implement2 the policy of benevolence3 of Confucianism and would do good turns to the people.Emperor Wudi Had hardly finished his remards when Ji An said that there was no need for the emperor to say so.Why should the emperor bother，Ji An said， about pretending to implement the policy of benevolence since he was so greedy and 4 within himself? This choked the emperor off. The emperor suddenly Changed his countenance5 and declared the meeting over. All the civilian6 and military officers at court were br of this. After returning， Emperor Wudi said to the people around him that Ji An was a little too rude and too straightforward7.
For this reason ， in charge of the appointment and dismissal of the local officials， both Gongsun Hong and Zhang Tang were low -ranking lfficials of little importance. Later ， Gongsun Hong became the prime minister and Zhang Tang became the imperial censor8. However， JiAn's post remained thesame. One day， like piling up firewood， surpassed the old-timers. Of course， So，turning to his ministers， Emperor Wudi said， "It is true that no one can stop learning.You see， Ji An is making more and more indiscreet remarks."
the set phrase " surpass the old-timers " can cxcel the predecessors9， which is quite different from the original idea when Ji An said that surpassed the old-timers.
