[Q] How to remove China Unicom bloatware and Google Play Store block topic

I recently bought a new phone, which is the Samsung Galaxy Fame Duos GT-S6812i. I'm the kind of person to actually play with his smartphone, so I tried updating my version. But updating my phone resulted in having a Chinese version (the only update) from China Unicom. Now I'm stuck with a bunch of chinese apps. I rooted my phone and I was able to remove most of them, but I just CAN NOT use Google Play.

Can anyone help me out removing the block

P.S: I also wish to have the China Unicom boot animation removed and the official Samsung boot animation back
