angular: angular2 router dose not work when “loadChildren” loading modules

I have a router definition like this:

const routes: Routes = [
{
    "path": "member",
    "loadChildren": "app/member/member.module#MemberModule"
},
{
    "path": "",
    "loadChildren": "app/video/video.module#VideoModule"
},
{
    "path": "**",
    "redirectTo": ""
}
]

MemberRouter definition like this:

const routes: Routes = [
{
    "path": "order",
    "component": MemberComponent,
    "loadChildren": "app/member/order/order.module#OrderModule"
},
{
    "path": "",
    "component": MemberComponent,
    "loadChildren": "app/member/index/index.module#IndexModule"
}
]

OrderRouter definition like this:

const routes: Routes = [
{
    "path": "list",
    "outlet": "member",
    "component": OrderComponent,
    "loadChildren": "app/member/order/list/list.module#ListModule"
},
{
    "path": "",
    "outlet": "member",
    "component": OrderComponent
}
]`

ListRouter definition like this:
`const routes: Routes = [
{
    "path": "",
    "outlet": "order",
    "component": ListComponent
}
]

It dose not work at “/member/order/list”

It is working at “/member/order”

“OrderRouter” rules can not be matched when “MemberRouter” is lazy loaded

“loadChildren” dose not work when nested

Please help me solve, thank you!
