Due to the need of recruitment, does the training unit have the obligation to pay wages before joining the company?

There is a charge for pre-job training.

The employing unit shall pay wages from the date of establishing labor relations with the workers, generally referring to the date when the term of the labor contract begins. According to the Labor Law, it is the legal obligation of the employer to provide pre-job training for skilled jobs. Pre-job training is a necessary procedure for employers to give full play to the skills of workers and serve them. It should be regarded as the cost that employers must pay, and pre-job training is generally arranged after employment. Therefore, according to the spirit of legislation, employers should pay wages in the pre-job training stage.
