Let’s suppose you are creating a travel website for different destinations around the world. You may want users to be able to find articles by city and by country as well.
假设您要为世界各地的不同目的地创建一个旅游网站。 您可能希望用户也能够按城市和国家查找文章。
For example, you can add United States and then post articles for New York City, Los Angeles, Chicago, etc. This is where you can utilize child categories. United States would become a parent category, and cities can become child categories.
例如，您可以添加美国，然后发布有关纽约市，洛杉矶，芝加哥等的文章。在这里，您可以利用子类别。 美国将成为父类别，城市将成为子类别。
It is important to note that a post filed under a child category does not need to be filed under parent category. For example, if you assign a post New York City as category which is a child category of United States, then you are free to choose whether you want the post to be filed under both or just the child category.
重要的是要注意，在子类别下提交的帖子无需在父类别下提交。 例如，如果您将职位纽约指定为美国的子类别，则可以自由选择是将帖子归档在两个子类别下还是仅在子类别下归档。
If you choose to file a post under the child category but not under the parent category, then your post will appear only on the archive pages of child category. This particularly helpful when you want to avoid duplicate content.
如果您选择在子类别下而不是在父类别下提交帖子，则您的帖子将仅出现在子类别的存档页面上。 当您要避免重复内容时，这特别有用。
Let’s suppose you have created a parent category United States and it has only one child category, New York City. Now if you file a post under both parent and child categories, then the archive pages of both categories will be completely identical.
假设您创建了一个父类别“美国”，并且只有一个子类别“纽约市”。 现在，如果您同时在父类别和子类别下提交帖子，那么这两个类别的存档页面将完全相同。
