Is it reasonable to pay the training fee of 15000 half a month before China Railway recruits people?

Unreasonable. In the Labor Contract Law, it is illegal for China Railway to recruit people for training for half a month and pay the training fee of 15000. Therefore, the company must bear the training fee itself.
