Tho, you can simply write on google "mangago tag"

go to any manga, scroll down until you see tags, click any tags and then search whatever tag you want. here's a direct link: http://www.mangago.zone/tag/

Go to any manga press on any one of the tags and it has a search bar then all u have to do is type in the tag you want :)

ty guys!

for list, same thing, (click any manga... click manga lists) but if you wanna find a specific list, you can search for list tag, unfortunately, not all lists have tags as it is optional

you can either use

OR
you can scroll down to any random manwha or manga and there should be a popular tag thing
click it and you should be able to search another one.
