How to show the post's data of some category first, and then the rest?

Hi, i need to retrieve certain data from the post – and showed one category’s post data first (preference) in the coupon’s list and then other categories post data second in the list.

I meant to say that suppose first 6 coupons are first preference, then it will be shown first then the rest. And then goes the pagination. Therefore as, i found on the internet – i try to use the 2 LOOPS for (one category & rest of the category respectively.

my website is https://www.coupon.mn

But the problem is even i click the second page, it is showing the first page data, not the rest of the data. Thanx in advance. I try to find answers through the internet no success, plz help.

I used the following code; plz help me what i am missing.

            $query1 = new WP_Query($args);      

            while($query1->have_posts() ) : $query1->the_post();
            $thumb = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
            $discount = get_post_meta($post->ID, '_single_discount', true);

            $url = get_post_meta($post->ID, '_single_url', true);
            $daysleft = round( ($date-time()) / 24 / 60 / 60);
