[help] post wont show after clicking the link/title

hi..iam a newbie in wordpress..

and now iam developing my own themes..

so here the problem..

i have post in my page..and when iam click it, it wont go to one page and display full post..(this post in home)

when i click it , it just go to same page as same as home..although the link in my browser changed..

example :

default address in my browser :https://localhost/wp/

then i click a post link, and then the address in my browser changed into : https://localhost/wp/?p=216 but the page is still same as this address https://localhost/wp/ .

here my code in html page where the post is shown :

<ul><li>
<a href=<?php the_permalink()?>"><?php the_title();?></a>
</li></ul>
how can i fix this?

if there’s any default plugin or something to instal first?
