If I were to implement a pizza ordering system, I would definitely write the code like this, because this kind of code can be written subconsciously without consuming our brains. However, take a closer look at this code: the purpose of this method is to order pizza. However, the code for ordering pizza also needs knowledge about the production of pizza. This method must know all pizza. Worse still, if the types of pizza are to be expanded or pizza with poor sales volume are to be deleted in the future, then the code for ordering pizza will be modified. It looks very bad and should be revised. Our first step must be to separate the code for producing Pizza from the code for ordering pizza, because you should not let the code for ordering Pizza know the logic for producing pizza, but should hand over the logic for producing Pizza to a special type. In this way, we can cope with future changes-if we want to add or delete pizza, we can directly modify the producer of pizza without affecting the logic of ordering pizza.　　静小姐在市井朋友万人敌的劝说下决定打劫齐国公的不义之财。不料找错了人，云南王之子、安宁公主的准驸马白云飞成了静公主等人的下手对象。静公主夺了白云飞的订亲镯子。朱允出宫后遇见了善心大发的静公主，他对这个仗义疏财颇受市井百姓该片讲述了一个不甘在酒吧做事的舞女茉莉卡，一心想要自由的生活，联合了3个陷入窘途的男人文哥、小强、胡少，他们准备策划一起抢劫案，这4个各怀鬼胎的人，一个想黑吃黑的债主玉姐，另外还有个虎视眈眈的酒吧老板黑龙，钱最终会落入谁手See Appendix A of GBL6408t 3 for inspection methods.也许换做杨寿全站在杨长帆的位置上，听到这里一嘴巴就抽过去了，什么狗屁理论？聊到天上去了？但杨长帆不是这样的，正是因为他拥有多得多的知识和见识，才愈发尊重每个人的思想，每个人的言论。
