Thank you all.

One experience: we need to closely monitor everything ourself. Lawyer won't help much. Also, we need to propose all posibilities to whoever (eg. company HR, managers, lawyer) aggressively. Don't think that others will help us by default even you are very well in work.资本家就是资本家。你的manager也是资本家，虽然他认为它的老板是资本家。
