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.老家大宅住着父亲老老头和三个儿子，长子老良、次子老非、老么老恭，还有一個人如其名的媳妇—贤淑。別看小老家一家五口，人口简单，其实在这五人身上，已包括了父子、夫妻及年轻男女的感情故事，这些故事不但充满笑料，亦深深令人感动。女主陆青青是个毛躁、直率的女孩，刚毕业对一切事物还处于懵懂状态，多次面试碰壁后领教过初来乍到的不容易！但是她妈妈李芳华有个海归朋友刘若雅是杂志公司的董事长，李芳华只好把女儿陆青青介绍朋友公司上班，结果一些误会让男主魏胜蓝母子俩看到。在两家聚会时刘若雅当着李芳华的面暗讽陆青青。家庭聚会闹得不欢而散。丢了面子的李芳华决心打造陆青青形象，否则一辈子不见刘若雅。起初陆青青不接受改变，还与其他同学闹不和，随着自身善良和慢慢理解母亲的用心良苦最终改掉毛病重获刘若雅和魏胜蓝的另眼相看。李芳华挽回面子两家人重新和好，陆青青和魏胜蓝也互相有好感。
