Below please find the code I currently works for the above jobs, but I still need the help in using the plugins because I need to do similar job at other pages with more complicated query.
// 8. Recent Posts
$args = array('posts_per_page' => 1, 'post_type' => 'post', 'category' => 'new-arrival');
$the_posts = get_posts($args);
echo "<div id='WeekCarPromo' class='col-md-6 margin-left-none padding-left-none'>";
echo "<div class='heading_bar'><img src='/images/heading_week_promo.png'></div>";
if(!empty($the_posts)){
foreach($the_posts as $single){
$return .= "<div class=\"thumb-image\">";
$return .= "<a href='" . get_permalink($single->ID) . "'><h4>" . $single->post_title . "</h4></a>";
if(has_post_thumbnail($single->ID)){
$return .= get_the_post_thumbnail( $single->ID, 'full', array('class' => 'recent_thumbnail') );
}
$return .= "</div>";
$return .= "<div class='car_details'>";
$return .= "<div class='post-row'>";
$return .= "<div class='post-col-2'>" . types_render_field("model", array("output"=>"raw", "post_id" => $single->ID)) . "</div>";
setlocale(LC_MONETARY, 'en_HK');
$fmt = "%i";
$return .= "<div class='post-col-2'>" . money_format($fmt, types_render_field("price", array("output"=>"raw", "post_id" => $single->ID))) . "</div>";
$return .= "</div>";
$return .= "</div>";
$return .= "<div class='car_details'>";
$return .= "<div class='post-row'>";
$return .= "<div class='post-col-3'>" . types_render_field("year", array("output"=>"raw", "post_id" => $single->ID)) . "</div>";
$return .= "<div class='post-col-3'>" . types_render_field("capacity", array("output"=>"raw",'show_name'=>'true', 'post_id' => $single->ID)) . "cc" . "</div>";
// $return .= "<div class='post-col-3'>" . types_render_field("capacity", array("output"=>"raw",'show_name'=>'true', 'post_id' => $single->ID)) . "cc" . "</div>";
$return .= "<div class='post-col-3'>" . types_render_field("mode", array("output"=>"html", 'show_name'=>'true', 'post_id'=> $single->ID)) . "</div>";
$return .= "</div>";
$return .= "<div class='post-row'>";

echo $return;
