Hi @phuocthinh832,
Looking on a default installation of WooCommerce only the star rating will display on product archive pages like this example using the Twenty Twelve theme.

This topic below which I found may help you with this.

Hey @phuocthinh832,
I managed to get the average rating count to display on product categories by overriding and editing the file woocommerce/templates/loop/rating.php
As a test I added the line echo $product->get_average_rating(); to that file like this example below. You would want to escape this output for security and also wrap it in some HTML so it can be styled and positioned if need be.

Below is a screenshot of the contextual rating displaying.

I hope this helps.
