How to root my android device?

I have a lenovo K900. Does anyone know how to safely root my android device? Any comments/advice would be helpful.

Here are some links for you, for further info I'd read through the forums:

I think the second one is maybe in chinese, might need to use chrome with translate to read it.

Anyway hope that helps.
