The next four patterns, including this pattern, are all the relationships between classes and do not involve inheritance. When learning, you should remember induction and the diagram at the beginning of this article. The observer mode is well understood, similar to email subscription and RSS subscription. When we browse some blogs or wikis, we often see RSS icons. This means that when you subscribe to the article, you will be notified in time if there are subsequent updates. In fact, in a nutshell, when an object changes, other objects that depend on the object will be notified and will change with it! Objects are a one-to-many relationship. Let's look at the diagram first:
The second step is to transform the Upload constructor and create an instance object for each state subclass in the constructor:

Since the 1920s, the influx of Western journalists into China has been like crucian carp crossing the river, but as far as the social status at that time is concerned, no one can expect Aban to match it. Aban is naturally competitive and can't compete for emergencies in the front line, but his real advantage lies in his extensive upper-level relations. The top level of the Chinese government and the top level of Japan, the United States, Britain, the Soviet Union and other countries in China are full of his personal friends. At the beginning, the national government wanted to expel him from the country, but later, all four families took him as their guest of honor. Japan attaches more importance to the fact that the top leaders of various factions and departments in civil and military affairs are eager to break through his threshold. The Soviet Union was also interesting. While setting off a wave of criticism of Aban, it sent an ambassador to talk with him in secret and entrusted him with conveying high-level meanings. As for the United States and Britain, it goes without saying. The importance of Aban lies in the fact that his role has completely gone beyond that of a mere reporter. To the U.S. Government, he is an unpaid senior intelligence agent, providing top secret information free of charge, weighing more than any official spy. To the rest of the governments, he is a supernumerary U.S. Diplomat, and his role is often beyond the reach of U.S. Ambassadors. Therefore, between Japan and the United States, between China and the United States, and between the United States and the United States, he has to send messages frequently. As for the infighting among various countries, they should also reveal their secrets to him so that they can be published in the New York Times and confuse each other. For example, before Japan officially joined the Axis, because of the confrontation between the two factions at the highest level, some people secretly told each other the news, which made him get a global super scoop for no reason. All this, of course, depends on the golden signboard of the New York Times and its inexhaustible resources.

Historically, intelligence gathering has been left to spies who risked their lives to sneak into a building (an organization, an embassy), steal documents, files or hard disks, and then run away. The more hidden these tasks are, the less likely they are to disturb the owners of these target files, and the better. Then, analysts or sometimes decoders decode the information so that military leaders and strategists can improve their attack plans to ensure maximum attack power.
