Any root for g9250(HK) 5.1.1?

I bought s6 edge g9250 from china, and i wanted to root it in order to install google play store and some root functions.
I have been searching the whole internet for weeks just for a root but i couldnt find it.
They said they dont have a root solution for boh2 version?
Please any help would be very appreciated. THANKS!
