"Is-A" refers to the "one" of one class and belongs to another class, while "Has-A" is different, which indicates that a certain role has a certain responsibility. A common reason for the wrong use of inheritance instead of aggregation is to mistakenly treat "Has-A" as "Is-A". For example:
马跃的妻子莉莉被绑架，龙卫三人在公安部门的协助下，抓捕了罪魁祸首，但莉莉已经被转移出境，交给了T国联络人。龙卫三人意识到这极有可能是黑狐的报复！T国发生示威游行，呼吁前总统坤恩重新执政。其实，真正的坤恩早已被黑狐软禁。黑狐是TM国际恐怖组织的一员，一直以来冒充坤恩，伺机夺取政权，骗取巨大的财富和权力。黑狐手下有一只精干的武装力量，其头目“獠牙”假扮记者告知雅塔，坤恩先生已经被救出。雅塔踏上寻父行程，发现中了圈套。龙卫三人赶赴T国，再次联手雅塔，潜入TM组织的秘密基地，与黑狐獠牙正面交锋！

2. As a Cheng Yuan who has been engaged in machine learning for more than two years, seeing the computer series you recommended also thinks it is very unreliable. I have read most of the books you recommended. In particular, novice readers are not recommended to read "Introduction to Algorithms" and "Data Mining: Concepts and Technologies". These two books are thick and heavy. Although the content is also good, you will not know the year of the monkey when you finish reading them. What does a novice need? It's getting started! Secondly, have you really finished reading Python Core Programming? This book is not for Python newcomers. It is very thick and difficult. It is very unfriendly to newcomers. And if you just want to be AI, then many parts of this book don't need to be used. Is web development and Django framework really necessary for our AI engineers? No. Xiao Bai has no distinction between key and non-key points in a book. He spent a lot of time learning unnecessary knowledge, which really does more harm than good. Giving guiding and targeted recommendations is responsible recommendation.

For today's journalists, Aban's book is more meaningful. It is like Sun Tzu's Art of War in interview studies. It teaches us how to use methods and smoke screens to accurately dig out news and publish news first in the complex changes. It also teaches us how to be strict with ourselves in professional ethics. Aban's personal emotional views are clear about love and hate, but the news report itself strives to be detached from the political disputes of the parties and the love and hate of the country and the nation. It has always kept the identity secret of the news source, no matter what party, faction or country it is. In terms of social activities, they are good at dancing with long sleeves and have both sides of the coin. They have become one with all walks of life at home and abroad, thus being able to dig up a large number of exclusive news. Even if he was kneeled on the ground by the Japanese gendarmes, his arms twisted to his back, and his waist and abdomen were kicked violently, even if the Japanese massacred thousands of his compatriots at Pearl Harbor, when his pen touched the Japanese, he could avoid emotional catharsis. The praise and the demotion were all treated impartially and directly, on a case-by-case basis and differently from person to person. Among journalists, this kind of everyone's demeanor makes people respect it.
