For codes of the same length, theoretically, the further the coding distance between any two categories, the stronger the error correction capability. Therefore, when the code length is small, the theoretical optimal code can be calculated according to this principle. However, it is difficult to effectively determine the optimal code when the code length is slightly larger. In fact, this is an NP-hard problem. However, we usually do not need to obtain theoretical optimal codes, because non-optimal codes can often produce good enough classifiers in practice. On the other hand, it is not that the better the theoretical properties of coding, the better the classification performance, because the machine learning problem involves many factors, such as dismantling multiple classes into two "class subsets", and the difficulty of distinguishing the two class subsets formed by different dismantling methods is often different, that is, the difficulty of the two classification problems caused by them is different. Therefore, one theory has a good quality of error correction, but it leads to a difficult coding for the two-classification problem, which is worse than the other theory, but it leads to a simpler coding for the two-classification problem, and it is hard to say which is better or weaker in the final performance of the model.

1949年的北京，国民党特务频繁作乱，一场大火烧掉了北平电车厂，让北京公共交通受损。战斗英雄出身的孙光大转业到公安局，与经验丰富但又一身坏习气的旧警察钱有根一起调查此案。在钱有根的帮助下，孙光大破获了一个一个重大的案件；孙光大帮助钱有根解救了赵春花，成立了家庭。钱有根的弟弟钱有财的死在孙光大、钱有根两人心中埋下化不开的误会。孙光大想解开这一切的误会、给钱有财平反，唯有抓住当事人张友一，可张友一异常的狡猾，数次逃过警察的搜捕。最后，孙光大终于抓住了张友一，钱有财的冤屈得到平反。钱有根经历一系列的波折，最终喜欢上了“对头”孙光大的儿子孙卫国，把孙卫国当成了自己的女婿、儿子，并把自己的破案绝学传授给孙卫国。孙光大和钱有根在国庆节的时候，终于把酒言欢、找回了兄弟情。
一九三七年十二月二十七日，中共山东省委在篦子店召开紧急会议，会议根据急剧变化的形势，决定在泰城被日寇攻占前正式举行起义。日军中佐滨野高广作为日军先头部队进入泰城境内。徂徕山崖头庄，正值村长杨守南次子杨东良大婚。在迎娶新娘胡腊梅的路上，杨东良等人遭遇了土匪头目鞠振山抢亲，年轻气盛的杨东良带人剿匪，却误打误撞杀死了两个日本侦察兵。杨守南大儿子杨东善带着省委的冯超等同志回崖头庄准备起义，被汉奸吕茂恒出卖，导致崖头庄被滨野高广带领的日军中队血洗。一九三八年一月一日，冯超、杨东善等人在徂徕山大寺召集各界爱国人士一百六十余人宣誓起义，成立“八路军鲁中抗日游击队第四支队”。杨东良和新婚妻子胡腊梅在冯超等人带领下，成功潜伏进泰城，破坏了日军的一系列战略计划，一举歼灭了滨野高广带领的日军部队。
