1935年国民政府为预备长期作战的后勤和经济准备，强制推行法币，停止银元、军用券、关金券等货币使用，为抵抗日军侵华做准备。对此，日本军方在哈尔滨秘密制造大量伪法币，搅乱金融和贸易秩序。日军称“黑猫计划”。针对日军的破坏，主管法币的财政部长宋子文派遣财政部直辖的税警总团副参谋长李道仁前往哈尔滨，目的为摧毁伪法币母版和制造所；同时，国民党派宋孝严，共同完成此项任务。日军派出土肥原和木户保卫“黑猫计划”，诛杀李道仁等人。敌我双方利用对方弱点，就此展开生死角逐。李道仁利用木户安插给自己的日本妻子掌握了木户的行动规律，通过对木户的跟踪，找到了伪币印制所，最终消毁母板，彻底粉粹了“黑猫计划” 。

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.
This is October 2014, when I was a company researcher at Lujiazui Finance House, when I first made a company research report, I encountered the scene. Three years have passed, and the situation at that time is still engraved in my heart. I clearly remember that in order to make this report, I spent half a month writing more than 20 pages of company research report, and spent a week staying up late until 11 o'clock to write a 70-page PPT with dense pictures and words, and a lecture draft of more than 10 pages. I also clearly remember the handsome boy who carried the bag halfway, with cold facial features and a young and fragile heart in his speech.
