每每心里不畅快的时候，我就对着天空和山峰大喊，然后回想起走过的山山水水，觉得自己就像芥子一样小，为一点事生气好无聊、好可笑。Decoct with water, boil for another hour, turn off the fire, and filter to obtain the first dye solution.Seventh fire facilities maintenance and testing institutions shall meet the following conditions:"Mice belong to rodents. It is indeed their natural nature to be good at digging holes and drilling the ground, but how efficient is it to use this skill to avoid fire on the spot?" I still couldn't believe it, so I continued to ask.康家一家住在广州西关老屋已经几十年了，康伯（龚锦堂 饰）、康婶（黄锦裳 饰）生了四个儿子，分别是祁光（苏志丹 饰）、祁宗（郭旭 饰）、祁耀（彭新智 饰）和祈祖（徐若琪 饰），四个儿子最近都结婚了，老大阿光娶了个河南姑娘（丁玲 饰）、老二阿宗娶了个本地姑娘（虎艳芬 饰）、老三阿耀娶了个上海姑娘、老四阿祖更厉害，娶了个德国姑娘（郝莲露 饰）。这下一屋子天南地北的人全集齐了，各地文化在此交融，地域、文化间的隔膜在这一大家庭里闹出不少笑话，康家几乎每天都是生活趣事Khaki: Guava, wormwood, mango, water chestnut, etcIf 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.
