Just an update, they finally did an upgrade of the contract, but it's worth it only for the full time, the part time side is still the last one in China. They also added something interesting (for them). "Just" 50000$ of penalty if you leave before the 3rd year....unfortunately is almost impossible to resist 3 years with this pirates.
They have no idea on how to keep people.
Much better company around China rather than Sichuan.
Have fun guys!!
