at * *'s instruction, liu bei was about to set off for a punitive1（惩罚的） expedition against yuan shu. before he left, liu bei worried about the defence of xuzhou city. when zhang fei volunteered to take the task, liu said, "how can i feel assured, when you're so fond of drinking and after drinking you always flog（鞭打） your soldiers for no reason. and you're such a hot-tempered person and frequently you refuse to take advice." he entrusted2 the task upon zhang only after the latter's repeated entreatments and resolutions to mend his ways. for safety, he left consultant3 chen deng to assist zhang.
one day zhang invited his subordinate officers over. "my elder brother instructed me before he left to stay away from wine for fear i may fail my duties to guard the city. let's have an final drinking party today, and starting from tomorrow, we will quit drinking and concentrate on the job." with these words said, he began toasting *ryone.
when neither of his toasts was accepted by * bao, zhang flared4 up. by then , zhang was already drunk. he had * flogged fifty times. after the party was over, the resentful * sent one of his men to lv bu, the enemy general, asking him to attack the city that night while zhang was drunk.
lv came with 500 horsemen. they succes*ully took the city. when zhang woke up with a start, the city was gone. he fought his way out of the enemy troops and fled the city, leaving his elder brother's family behind. when he met liu, he felt so shame-faced that he unsheathed（拔出鞘） his sword meaning to commit *, only to be stopped by his elder brother.
