Legal analysis: it depends on the training course and can be settled through consultation. Some training courses will be fully refunded for credibility. However, it is still necessary to negotiate early. If the school has arranged all the teachers' courses, it's hard to say, but most of them will not be refunded in full, just a part. It is illegal to collect training deposit.

Legal basis: Article 9 of the Labor Contract Law of People's Republic of China (PRC), the employing unit shall not detain the employee's resident identity card and other documents, and shall not require the employee to provide guarantee or collect property from the employee in other names.
