There any solution that let me embed below site videos into my ips website? I would like have these resources for my community members, daily life sharing what we love watch with others.

There's not going to be a "built in" solution. What I think you could do is

1. Create a custom editor button that lets you paste the URL in, and it turns into an iframe tag in the editor.
2. Under Customization > Editor > Settings in the AdminCP, on the Advanced tab you'll need to add a new iframe base to allow your custom video URLs to be retained during submit.

Not so easy with that site too, they are protecting their content very good. Finding the sources on other video sites is much easier 

They also don't offer embedding in their sharing options, only the link with description.
