Wordpress classification and tag link prefix optimization

In the process of building a new website with wordpress, I found that the tag page always has a tag in front of it, like this: iidns.net/tag/inverse campaign, the category page also has category in front of the directory name, which is a headache , I looked for a tutorial on the Internet, and said that it was to remove the prefix of the sub-zhi category and the label dao link by directly modifying the fixed link du connection setting in the wordpress background bai. The specific operation method is to add one in the setting-fixed link-category directory prefix Click .or ./, after actual testing, this will lead to a 404 in the category or tab page, and further configuration of Rewrite is required to complicate the original simple method.
So how to deal with it simply?
1. Use the optimization function that comes with the theme.
2. Use wpjam plugin, wordpress plugin author and prominent blogger: I love boiled fish works, his website loading speed in the following 1S can be said that this plugin denied.
3. I still modify the code, but I gave up after repeated attempts, because the rewrite rules I set may conflict with the rules added later, and I failed to set it several times, and my head was bald...
