I was wondering how to set the post per page.
Now I see it from Setting.
Many thanks!
Sorry for the delay.
Thanks, vtxyzzy for the big help.
Although I didn’t get your suggestion work, I can see the hint.
Now I have removed the WP_Query and use the parent query. It works perfectly and show the post of current category only.

On the other hand, however, I don’t know how can I have them in 4-post a page.
Many Thanks!
