Thank you for your time answering my unclear question. The code I found is the one that Im looking for. Thank you again 🙂
<?php
//http://codex.wordpress.org/Function_Reference/WP_Query#Taxonomy_Parameters
$term_slug = get_queried_object()->slug;
if ( !$term_slug )
return;
else
$args = array(
'tax_query' => array(
array(
'taxonomy' => 'gallery_category',
'field' => 'slug',
'terms' => $term_slug,
'posts_per_page' => 10
)
)
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); ?>
<div class="entry-content">
<?php the_excerpt(); ?>
</div><!-- .entry-content -->
<?php endwhile; // End the loop. ?>
