Legal analysis: you can take it away. This is the employee's own certificate and can be taken away. However, if there is another agreement between the unit and the employee during the training verification, the agreement shall prevail. Ordinary employees need to compensate part of the training expenses of the unit. If the employing unit detains the employee's resident identity card and other documents, the labor administrative department shall order it to return the employee himself within a time limit and impose penalties in accordance with relevant laws and regulations.

Legal basis: Article 22 of People's Republic of China (PRC) Labor Contract Law. Where an employer provides special training fees for laborers and provides them with professional and technical training, it may conclude an agreement with the laborers to stipulate the service period. If the laborer violates the service period agreement, he shall pay liquidated damages to the employer in accordance with the agreement. The amount of liquidated damages shall not exceed the training expenses provided by the employer. The liquidated damages that the employer requires the laborer to pay shall not exceed the training expenses that should be shared for the unfinished part of the service period. If the employer and the employee agree on the service period, it will not affect the employee's improvement of labor remuneration in accordance with the normal wage adjustment mechanism during the service period.
