Exclude Custom Taxonomy Term Posts from Custom Posts Query

Custom post has been a very useful capability in WordPress. It makes it much more easier to organise custom content in WordPress as a CMS. For custom post, we can use tax_query to filter unwanted categories or display custom post of certain categories. It's fully configuration and you can combine multiple query too.
