In order to decouple, the Mediator class is introduced to provide unified interface, and MyMediator is its implementation class, which holds instances of User1 and User2 to control User1 and User2. In this way, User1 and User2 objects are independent of each other. They only need to maintain a good relationship with the Mediator, and the rest is maintained by the MyMediator class!

One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.

Regarding the signing of the Sino-US tariff treaty, Aban also added details to the readers. It was precisely because of the administrative disorder of the National Government that the US Government offered to return the tariff autonomy to China, but it was mistakenly put by the relevant departments for 18 months and was not known by the senior officials. It was not until Song Ziwen met with US Minister Mamuri that he realized the existence of the incident and stepped up the signing. Therefore, the Treaty on Sorting out Tariff Relations between China and the United States was signed by Finance Minister Song Ziwen. The new tariff treaties with other big powers were signed by Foreign Minister Wang Zhengting.

主控了CW半个江山的Greg Berlanti，联同夫妇Mara Brock Akil及Salim Akil开发DC英雄剧《黑霹雳 Black Lightning》，该角色由Tony Isabella与Trevor Von Eeden创造，原先由FOX以试映集制作协议拿下该项目，但现在确定改交给CW并被预订试映集。据指这是因为FOX认为现有的剧，加上其他试映集，《黑霹雳》会挤不进拥挤的档期。这也不是CW第一次拾人家的项目，例如《河谷镇 Riverdale》原先是FOX的项目﹑从CBS接手的《超级少女 Supergirl》﹑在Showtime要来的《疯狂前女友 Crazy Ex-Girlfriend》等。《黑霹雳》由Akil夫妇当编剧，黑霹雳本名Jefferson Michael Pierce，在剧中他停止当英雄多年，但因为他女儿对正义上的固执，以及他的一位明星学生被拉进当地黑帮，令他只好重出江湖，再次当起义警 - 黑霹雳。如果成功预订成剧的话，这将会是无线网唯一以黑人角色主导的英雄剧。（算上全部媒体的话，Netflix的《卢克•凯奇 Marvel's Luke Cage》是另一部。） 在DC漫画中黑霹雳这角色在1977初登场，是首位主要黑人英雄，本人是名奥运会十项全能金牌得主，可以从指尖生成强力的电池能量球，他表面是位深受爱戴的老师，而另一面则是化身成正义联盟的英雄黑霹雳。他有两个女儿，Anissa（第三代雷电）﹑Jennifer（第三代闪电），分别是局外人战队及美国正义协会成员。
