如何调用一个在React中作为道具传递的组件？

import ChildComponent from './ChildComponent';

class ParentComponent extends React.Component {
  render() {
    return (
      <div>
        <ChildComponent />
      </div>
    );
  }
}

class ChildComponent extends React.Component {
  render() {
    return (
      <div>
        <h1>{this.props.title}</h1>
        <p>{this.props.description}</p>
      </div>
    );
  }
}

class ParentComponent extends React.Component {
  render() {
    return (
      <div>
        <ChildComponent title="标题" description="描述" />
      </div>
    );
  }
}
