The most effective and comfortable way to run a business is to use fishing, just like when we first started chasing girls, would we chase several girls at the same time and then have a success in Bo? We will look at one and pursue her until we succeed. This is how I run my own business. I will choose one industry, for example, I want to be an earphone industry. I will choose about three of the industries to attack him seriously until I do it. The others will be very good in the future. In this way, when you account for 80% of the earphone industry, we will switch to other industries and copy it, just like fishing. It is very comfortable to catch large ones one by one.　　另一方面，女警Rainbow被男友警司张大卫利用，进行偷运毒品活动，纯真的她本以为可藉此机会助男友平步青云，继而使他与其妻离婚选择自己。随后，燕来港无以为生，乃操皮肉生涯，但在一次扫黄行动中被捕；大卫认为可借助她替毒贩运毒，遂设下圈套。《I:LOVE:DM》讲述接受私信投稿代替苦恼代替恋爱商谈的I艺高广播部校园爱情网剧。一个国破家亡的年代,一首血雨腥风悲歌。战火纷飞的1940年，国民党已撤至重庆，共产党据守延安，日本侵略军正在猖獗。灵湖镇上的人们不曾预料到的是，在战火蔓延至身边之际，一场瘟疫又将侵袭。而一个无计维生的人会救他们于危难，同时，这个人也将灵湖镇拖入了一场血腥风雨的暗战中。一声枪响，打破了小镇的宁静，也惊吓到任旭棠。受到枪吓的任旭棠慌忙逃回家中，谁知，那被追杀之人却找上门来，此人是土匪头子宋大哥。追杀宋大哥的是当地保安团。保安团的刘团长乃是信奉有枪便是草头王的土皇帝。他一面忙于“剿匪”，一面却不忘美色。刘团长看中了镇长百年药店乐缘堂家的大小姐丁秋萍，于是派媒人前来提亲，实际上就是逼婚。丁秋萍是一个受过高等教育的新派女青年，胸怀抗日救国理想，丁秋萍自然不会受刘团长的要挟，与之顽抗到底。不久，这小镇的日军也将难逃瘟疫的魔掌。本是医药世家之后的任旭棠，凭借自己研发的药方,救了日本司令部长官山本太郎夫人的命,得到了山本太郎的赏识,见识到三天九天汤神奇疗效的日本军人冈野,开始打起了药方的主意方的成功,更谢谢你们。In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.
