+
+## GetRef
+
+Get the `ref` property definition of the component, which is very useful for components that are not directly exposed or child components.
+
+```tsx
+import type { GetRef, Select } from 'antd';
+
+type SelectRefType = GetRef<typeof Select>; // BaseSelectRef
+```
+
+## GetProps
+
+Get the `props` property definition of the component:
+
+```tsx
+import type { Checkbox, GetProps } from 'antd';
+
+type CheckboxGroupType = GetProps<typeof Checkbox.Group>;
+```
+
+## GetProp
+
+Get the single `props` property definition of the component. It has encapsulated `NonNullable`, so you don't have to worry about being empty:
+
+```tsx
+import type { GetProp, Select, SelectProps } from 'antd';
+
+// Both of this can work
+type SelectOptionType1 = GetProp<SelectProps, 'options'>[number];
+type SelectOptionType2 = GetProp<typeof Select, 'options'>[number];
+```

+
+## GetRef
+
+获取组件的 `ref` 属性定义，这对于未直接暴露或者子组件的 `ref` 属性定义非常有用。
+
+```tsx
+import type { GetRef, Select } from 'antd';
+
+type SelectRefType = GetRef<typeof Select>; // BaseSelectRef
+```
+
+## GetProps
+
+获取组件的 `props` 属性定义：
+
+```tsx
+import type { Checkbox, GetProps } from 'antd';
+
+type CheckboxGroupType = GetProps<typeof Checkbox.Group>;
+```
+
+## GetProp
+
+获取组件的单个 `props` 属性定义。它已经将 `NonNullable` 进行了封装，所以不用在考虑为空的情况：
+
+```tsx
+import type { GetProp, Select, SelectProps } from 'antd';
+
+// 以下两种都可以生效
+type SelectOptionType1 = GetProp<SelectProps, 'options'>[number];
+type SelectOptionType2 = GetProp<typeof Select, 'options'>[number];
+```
