Huawei Honor 6X Emui 5.0 Android 7.0. Not Core GMS package problem

I live in the UK. I got a Chinese phone where I can not run Google apps. Having to install a Core GMS package in order to do this?

Huawei Honor 6X Emui 5.0 Android 7.0.

Is there anyone who has useful information about how to do this? Was ages searching in forums and nothing worked.

Thanks everyone
