My /var was almost full and I use Bleachbit to clean up , Before run Bleachbit it was 77% and after running Bleachbit to clean up , it still 66%

Anyone could help me ?

What about your log files? Did bleachbit touch those? Run journalctl --disk-usage to learn more. (They are located in /var/log/journal and usually occupy a lot of space).

journalctl --disk-usage Archived and active journals take up 168.8M in the file system.

If you think you don't need the log files anymore and if the 170M is significant in your case: sudo rm -rf /var/log/journal/*

A short command to list 20 directories in /var which are using more space :

$ sudo du -ah /var/* 2>/dev/null | sort -rh | head -n 20

Are you using clamav? If not, get rid of all the clamav stuff. Are you using PackageKit (Gnome Software)? If you are using dnf instead (what you should), delete /var/cache/PackageKit/* and mask (disable) the PackageKit service. You can also delete /var/spool/abrt/ccpp-2018-03-07-20:46:09.575431-2374 and the corresponding coredump. As well as /var/cache/fedy/jre/jre-8u161-linux-x64.rpm.

Also, consider increasing your /var to at least 5 GB. Is there a special reason why you have /var on a separate partition?

Thanks for your advice , but i get confused now because i am not IT guy, what command i should run for those things ? Please help , i just want to make my root and swap have more space so i did seperate on /var , /tmp , hehe

Command: sudo rm -rf /var/cache/PackageKit/*

... and so on for the others. You may want to make yourself familiar with the sudo and rm command (among others). Also, as long as you don't need it and don't have a clear picture of large each partition should be, and don't separate /var and /tmp and maybe not even swap (use swap file on / instead) - that way you actually waste less space (20-30 gb / incl /var is sufficient in most cases). You want a large /home. Keep the rest together.

If you think you don't need your past logs: sudo rm -rf /var/log/journal/*

A common issue is a lot of stale files in /var/cache/PackageKit. Try running du -hd2 /var to find out where the space is being used.

Update: Is your /var a separate partition? You're only using 1.2GB in /var which is very little. Unless it is separate, which is unlikely, it's your root (/) partition that is full.
