如何在 React 中更新父级的状态？ - How can I update the parent's state in React?

问题：

My structure looks as follows:我的结构如下：

Component 1

 - |- Component 2


 - - |- Component 4


 - - -  |- Component 5

Component 3

Component 3 should display some data depending on state of Component 5.组件 3 应根据组件 5 的状态显示一些数据。

Since props are immutable, I can't simply save its state in Component 1 and forward it, right?由于 props 是不可变的，我不能简单地将它的状态保存在组件 1 中并转发它，对吗？ And yes, I've read about Redux , but I don't want to use it.是的，我读过Redux ，但我不想使用它。 I hope that it's possible to solve it just with react.我希望可以通过反应来解决它。 Am I wrong?我错了吗？
