Legal analysis: wages are calculated from the date when the labor contract begins. As for the training period, working hours are not counted and wages are not paid. Whether the employer should pay the wages of employees during the pre-job training depends on whether there is a labor relationship between the employer and employees.

Legal basis: Article 7 of the Labor Contract Law of People's Republic of China (PRC), the employing unit establishes labor relations with laborers from the date of employment. The employing unit shall establish a roster of employees for future reference.
