So, after I've heard so many complaints and could recognize his wrong acting several times by myself, I decided to kick Hang out of our Clan.
Hang, I had warned you so many times but you can't stand a fair behaviour, that's why I have to kick you out.
Though, thanks for all you've done for the clan but I won't acquiesce this intern and external fights anymore.
Good luck in your future!
ps: Could some admin delete him from devils group? Thanks
