Could you tell me how to use loadChildren?

I wrote the route in app-routing.module.ts:
{

    path: "about",
    component: AboutComponent,
    children: [
        {
            path: "about/componyinstroduction",
            loadChildren: "../pages/about/about.module-sharpComponyinstroductionComponent"
        },
        {
            path: "about/teaminstroductionComponent",
            loadChildren: "../pages/about/about.module-sharpTeaminstroductionComponent"
        },
        {
            path: "about/honourComponent",
            loadChildren: "../pages/about/about.module-sharpHonourComponent"
        },
        {
            path: "about/structureComponent",
            loadChildren: "../pages/about/about.module-sharpStructureComponent"
        },
        {
            path: "about/structureComponent",
            loadChildren: "../pages/about/about.module-sharpStructureComponent"
        },
    ]
