2. Whether it is against the law if the employer deducts the 6% contribution of labor pension from my wages? And what should I do to protect my rights?

It is against the Labor Pension Act, which regulates that the contribution should be paid totally by the employer. If the employer deducts the contribution from your wages, it already constitutes incomplete performance of wage payment and violates the Labor Standards Act. Then you may prepare related information and data and report the situation directly to the labor affair administrative competent authorities located at the place where the service unit locates (Country or City Labor Bureau or Labor department).
