## zh-CN

当 `RangePicker` 无法满足业务需求时，可以使用两个 `DatePicker` 实现类似的功能。
> * 通过设置 `disabledDate` 方法，来约束开始和结束日期。
> * 通过 `open` `onOpenChange` 来优化交互。

## en-US

When `RangePicker` is not satisfied your requirements, try to implement similar functionality with two `DatePicker`.
> * Use the `disabledDate` property to limit the start and end dates.
> * Imporve user experience with `open` `onOpenChange`.
