Hello @869140255qq-com,

First of all thank you very much for using the pro version.

Also once you activate the theme you will get the list of posts in the home. So to change it into the structure as shown in the demo at first you need to manage your homepage settings.

For this go to Admin Panel > Appearance > Customize > Homepage Settings and set the Homepage displays to “A static Page” and set the pages for the front page and blog page.

Now, you have to set up the sections through customize screen.

To help you setup your site we have the theme’s official documentation which you can refer.

Thank you.

Regards!!
