Simply, very simply.
很简单，很简单。
//firstly, load data for your child category
$child = get_category(31);
//from your child category, grab parent ID
$parent = $child->parent;
//load object for parent category
$parent_name = get_category($parent);
//grab a category name
$parent_name = $parent_name->name;
Study get_category
学习 get_category

$thiscat = get_query_var('cat'); // The id of the current category
$catobject = get_category($thiscat,false); // Get the Category object by the id of current category
$parentcat = $catobject->category_parent; // the id of the parent category

<?php
if (is_category())
{
$thiscat = get_category( get_query_var( 'cat' ) );
$catid = $thiscat->cat_ID;
$parent = $thiscat->category_parent;
if (!empty ($catid) ) {
$catlist = get_categories(
array(
'child_of' => $catid,
'orderby' => 'id',
'order' => 'ASC',
'exclude' => $parent,
'hide_empty' => '0'
) );
?>
<div class="subcat-list">
<ul>
<?php foreach ($catlist as $category) { ?>
<li><a href="<?php echo get_category_link( $category->term_id ); ?>"><?php echo $category->name; ?></a></li>
<?php } ?>
</ul>
</div>
<?php } } ?>
