I suffered 2 years and finally realized no matter how much effort I did the other party just thought his way was good one to push for more (a wellknown method).
Before entering this prison, I worked for another good company. It was my biggest mistake to quit the company.
My experience: (1)take 2-3 weeks vacations before quit, (2) join new company, if anything wrong, quit and go back to the previous company,
