You could find posts here.
You might notice that there is a search bar below, which could provide a “global search” for all the posts on this website. Within a category page, there is also a “local” search bar with which you can investigate contents under this category. WordPress doesn’t provide a modifiable auto-generated template for category page (and also for 404 page) so I had to edit some php/css file with my limited knowledge of html/php languages. More functions are coming soon!
