 ## FAQ
 
-Please ref [Tooltip FAQ](/components/tooltip#faq).
+### Why does the warning findDOMNode is deprecated some times appear in strict mode?
+
+This is due to the implementation of `rc-trigger`. `rc-trigger` forces children to accept ref, otherwise it will fall back to findDOMNode, so children need to be native html tags. If not, you need to use `React. forwardRef` transparently passes `ref` to native html tags.

+### Why sometime not work on HOC?
+
+Please ensure that the child node of `Tooltip` accepts `onMouseEnter`, `onMouseLeave`, `onPointerEnter`, `onPointerLeave`, `onFocus`, `onClick` events.

 ## FAQ
 
-请参考 [Tooltip FAQ](/components/tooltip#faq)。
+### 为何在严格模式中有时候会出现 findDOMNode is deprecated 这个警告？
+
+这是由于 `rc-trigger` 的实现方式导致的，`rc-trigger` 强制要求 children 能够接受 ref，否则就会 fallback 到 findDOMNode，所以 children 需要是原生 html 标签，如果不是，则需要使用 `React.forwardRef` 把 `ref` 透传到原生 html 标签。
+
+### 为何有时候 HOC 组件无法生效？
+
+请确保 `Popover` 的子元素能接受 `onMouseEnter`、`onMouseLeave`、`onPointerEnter`、`onPointerLeave`、`onFocus`、`onClick` 事件。
