Phone bought in China, can't access apps?

[userdfKo2hZoqY]

I bought phone in China, Astrill and google play were installed the same day and google play stoped working after 2 weeks, I can’t login other apps like instagram or Facebook, Viber, youtube also not working. I tried to change the country as suggested from Samsung support but still can’t find these apps on galaxy store. 

Is phone sold in china different than anywhere else?

How to fix this problem? 

And Why do I see only Chinese app?

Thank you

The phone sold in China is different as they don't have any deals with Google. They have their own everything
