The combination mode is also called part-to-whole mode. The combination mode combines objects into a tree structure, which is used to represent the relationship between the whole and the part. The combination mode enables clients to treat individual objects and combined objects equally. For example, in. NET, simple controls such as WinForm controls, TextBox and Label inherit from the Control class, while composite controls such as GroupBox also inherit from the Control class. The specific structure diagram of the combination mode is shown below.

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.
