　　两人住在一起后，敬文一步步得知舅舅奇幻精彩的冒险，以及他对 SEGA 电玩的痴狂。然而，有时听着舅舅孤单又残酷的遭遇，让敬文在开心的同时，也为他感到难过。Arranged by practicality:(4) There is no infectious disease, and I and my family have no history of mental illness.他也不好拦着，庄户人家没那么多规矩，也抹不开这个脸面，只能跑快些去告诉太太，横竖张家门口还有刘管家和护院们守着，那才是门房，他不过是护林的。那汉子就急了，嘴里发出一声猫头鹰般的鬼叫，就有另一个猎户打扮的人从旁边树林子里钻出来，也不上来帮忙，却冲着山洞跑过去。This pseudocode can well understand the event delivery mechanism: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.
