 ### Parent 父子
 ```csharp
-class order {
-    public int id { get; set; }
+class Group {
+    public int Id { get; set; } //Id、GroupId、Group_id
 
-    public int parentid { get; set; } //parentid、parent_id
-    public order parent { get; set; }
+    public int ParentId { get; set; } //ParentId、Parent_id
+    public Tag Parent { get; set; }
 
-    public ICollection<item> orders { get; set; }
+    public ICollection<Group> Childs { get; set; }
 }
 ```
 
+父子关系，与一对多其实差不多，添加数据参数上面的连接；
