Is that category empty? By default WordPress hides emptr categories. try:
那个类别是空的吗？默认情况下，WordPress 隐藏 emptr 类别。尝试：
$categories = get_categories('child_of=2&hide_empty=0');
Edit:Fixed, thank you @Stoep
编辑：已修复，谢谢@Stoep

The child_ofargument of get_categoriesspecifies the category by it's ID - assuming you created your categories in order, the code get_categories('child_of=2')is probably requesting the subcategories of Sub1OfTest1.
的child_of参数get_categories通过其 ID 指定类别 - 假设您按顺序创建了类别，代码get_categories('child_of=2')可能正在请求 Sub1OfTest1 的子类别。
To get the ID of a category, go to Posts → Categories and click on a category. The cat_ID will be in the url of the page.
要获取类别的 ID，请转到帖子 → 类别并单击一个类别。cat_ID 将在页面的 url 中。

try this too - Show wordpress subcategories only
也试试这个 -只显示 wordpress 子类别
that topic might help too, as there are different solutions for showing subcategories.
该主题也可能有所帮助，因为显示子类别有不同的解决方案。
