React uses children to nest components, how to get the parent component props

background description: if you want to nest components through children, how to get props

I know to change the following map, but I haven"t learned it yet and I don"t know how to change it. I also know that writing HomeHeader into HomePage components can solve the problem, but I hope it can be more elegant, nested in children, and look more comfortable in index.

question: how does HomeHeader get the props.config in HomePage

the code is as follows 

// 
<HomePage>
  <HomeHeader />
</HomePage>


// 
// HomePage
static defaultProps = {
  config: "aaa"
}

<div>
  {React.Children.map(children, child => {
    return child
  })}
</div>

//  
// HomeHeader
<div>
  header
</div>
React.js
Mar.30,2021 
<div>
  {React.Children.map(children, child => {
    return React.cloneElement(child,
         {
           config: this.props.config
         },
     );
  })}
</div>

HomeHeader directly this.props.config value

pass it down through props 

// 
// HomePage
static defaultProps = {
  config: 'aaa'
}

<div>
  {React.Children.map(children, Child => {
    return <Child config={config}/>
  })}
</div>

//  
// HomeHeader
<div>
  header
</div>


// 
<HomePage>
  <HomeHeader />
</HomePage>
