After a few days scratching head and crying loud trying to find out why when i open Google Play Store it's just stuck on circular loading screen, i finally came down to the solution. For all of you who think it's maybe ROM's fault, it's not.
It's pure GApps' fault, specifically it's com.google.android.gms A.K.A Google Play Services.
Not long ago, you can find an app named GMS Installer in HiApp market, and Huawei decided to trash it, so that's why you can't find it anymore in HiApp market.
GMS Installer is the solution for this issue.
