三人行必有我师 孔子曰“三人行，则必有我师。” 是故弟子不必不如师，师不必贤于弟子。 闻道有先后，术业有专攻，如是而已。 Confucius said "If three men are walking together, one of them is bound to be good enough to be my teacher." A student is not necessarily inferior to his teacher, nor does a teacher necessarily be more virtuous and talented than his student． The real fact is that one might have learned the doctrine earlier than the other, or might be a master in his own special field．
