Default Root for Chineese Phone: Citric C3

Hi all!
I've bought a new cell phone to my gf from China because it seems a good deal (it's small, good loking, dual core..), but in the specs says 512mb ROM... when actually it only has 109mb ROM, so she only could install WhatsApp and Facebook.

What I think, is that if i get root access, i could move some apps to the SD card (4gb) and then she might be able to install some other things (at least some basic game)

Could you please help me to get root Access? or maybe to flash it and get some other ROM that uses less space

The Phone Specs are:
CPU: MTK6572W, Cortex A7 dual core: DualCore ARMv7
Model: Citric C3
Android Version: 4.2.2
BuildNumber: ALPS.JB3.MP.V1
Kernel: 3.4.5 otd@otd-desktop #1

Thanks in advance,

Rodrigo
