showing tag beside catagory

Paste this code along side the code given by you
I have not tested the code but it should do the trick…

where you used this [blog1 items=1 cat=op-ed] replace this with this [blogtag items=1 tag=china]

  <?php
$queried_object = get_queried_object();
$term = $queried_object->name;
add_shortcode("blogtag", "blog_tag");



function blog_tag($atts, $content) {

    extract(shortcode_atts(array(

        "items" => 4,

        "order" => "desc",

        "orderby" => "DATE",

        "events" => null

    ), $atts));
