尝试依赖新的WP\\u Term\\u Query（）类，下面是针对您的代码的示例：

 // WP_Term_Query arguments
$args = array( 
                \'taxonomy\'  => \'carabana_Cat\', 
                \'hide_empty\' => false, 
                \'orderby\' => \'description\', 
                \'child_of\' => 28) 
                );

// The Term Query
$term_query = new WP_Term_Query( $args );
